2) 被固體狀態樣品捕捉的分析物,例如被捕捉於金屬箔 片中的氮, 3) 基材表面的被吸附物,例如催化金屬表面的自由基; 10 1292822 4) 生物分子,例如蛋白質,核酸碎片,聚醣、脂質、糖 蛋白、荷爾蒙、寡核酸及抗體; 5) 生物分子錯合物,例如DNA-蛋白質錯合物與蛋白質 -蛋白質錯合物; ' 6) 有機聚合物,例如聚笨乙烯及聚乙二醇; 7) 奈米級及微米級粒子,包含量子點及聚苯乙烯粒子體 積標準品; 8) 在表面的團簇或氣溶膠,特別是環境應用基材收集之 微米/奈米粒子; 9) 胞器,例如染色體或粒腺體; 10) 細胞,例如病毒、細菌和紅血球; 11) 類菌質體;及 12) 金屬與無機團藤(clusters)及粒子。 其他類型的分子也可被聲波脫附,且被提供於本發明 所述之質譜分析。 回到第一圖與第二圖中,聲波源109係設置用以造成 利用一稱做雷射誘導聲波脫附(Laser-Induced Acoustic Desorption,LIAD)技#f將樣品105之分子的聲波脫附。如 圖所示,聲波源109包含一電磁波源,例如一脈衝紫外光 雷射106,以提供基材104能量誘發基材内的聲波。一合適 的脈衝紫外光雷射106係為一頻率兩倍於Nd : YAG的雷 射。聲波源109也包含基材104,樣品105係設置於基材之 表面藉以接近進入QIT 102的開口處。雷射光束可利用聚焦 鏡107聚焦於基材上。雷射1〇6的光束係導引至基材未設 置樣品105之側。因此,樣品1〇5並無直接與雷射光束接 1292822 觸,且其可因此免於因直接暴露於雷射輻射造成之傷害。 弟二圖係為一利用雷射誘導聲波脫附技術之分子脫附 程序的示意圖。如圖所示,由雷射源1〇6來的雷射光束310 直擊設置有樣品105的基材1〇4的表面320,且可得知,樣 品105係設置於並未直接與雷射光束31〇接觸之表面322。 雷射的強度所致之光束流(即雷射能量密度)係高於 剝落門檻(即材料吸收雷射能量能成功打斷材料之分子間 鍵結的能量點)。被吸收的雷射光束因此造成物質排列於 基材上的鍵結被破壞。如第一圖之插圖所示,其係為 基材104之表面320上的半徑接近1 mm的雷射剝離點。 當物質與基材104間的鍵結被破壞後,產生的衝擊波 穿過基材直到抵達表面322。穿透波的能量傳遞到樣品1〇5 中的至少部分分子。於是能量被分子獲得後造成部分分子 由樣品105主體被脫附。由第三圖進一步來看,部分被脫 ^的分I包含中性分子(以白色圓呈現),而部分被脫附 分帶,荷分子(以黑色圓呈現)。被脫附分子中只有 部^帶電荷分子會被一離子阱質譜儀的電場捕捉 ,同時中 性分子並不會被電場影響。儘管圖未顯示,一聲波換能器 可用來監測聲波的成果。例如,可監測聲波脫附程序。 ―為了促進基材内震動波的產生,基材104係由具有一 剝落門檻低於所使用之雷射強度的材料所構成。用來做為 基材的&適材料係為;g夕,也可使用其他具有適合之剝落門 檻或其他可令其適合誘導材料内震動波特性之材料。 在部分實施態樣中(圖未呈現)’聲波源109包含-粒子束產生器(例如—電子束)。粒子束誘發基材内聲波 12 1292822 使樣品105脫附分子。以雷射光束為例,當光束流程度超 於基材剝落門檻值時,粒子束對基材上的輻射造成基材内 物質的破壞。其結果係使基材内產生震動波並穿透基材。 當震動波抵達沈積之樣品之表面時,震動波脫附至少部 的分子。 在部分實施態樣中(圖未呈現),聲波源1〇9包含一 可造成機械震動之壓電元件。在這些實施態樣中,一控制 器發出電子訊號至壓電元件,造成壓電元件根據訊號強度 啟動元件發生機械位移。壓電元件係位於接近相對於樣品 分子沈積之基材表面之相對表面附近。當壓電元件機械Z 移時,其打擊基材或基盤,因此造成聲波或震動波的產生 並穿透基材。這些穿透波抵達基材上沈積有分子樣品之表 面時造成至少部分分子由樣品中被脫附。可被啟動以產生 機械震動並傳遞至基材之其他類型的元件也可被使用。 在部分實施態樣中,聲波產生器可用以產生直接投射 至樣品上的聲波。因此,產生的聲波無需穿透其他介質, 且聲波的產生並未透過入射光束(粒子束或光束)誘發基 材内震動波的中間程序,或者產生機械震動以製造基材内 振動。在部分實施態樣中,聲波產生器係可為連續音波源、 超音波源及或脈衝聲波源。因此產生的聲波被投射至設置 於容器或基材上之分子樣品。當聲波擊中樣品,其傳遞聲 波能量至分子,其結果係至少部分分子獲得足夠動能驅使 其由樣品中脫附。至少部分被脫附的分子為帶電荷分子, 因此那些分子可進行質譜分析。在部分實施態樣中,被脫 附分子將因此具有一與分子樣品105内實質上相同之電荷 13 1292822 分佈。 儘管此處所述之聲波脫附技術的使用並不需要離子化 程序用將分子樣品105離子化。在部分情況下,樣品的離 子化仍然可以實行。舉例來說,在部分例子中需要較大量 的帶電荷分子。例如,當聲波脫附係藉由直接投射入射聲 波能量至樣品105 (例如使用連續聲波源、超音波源及/或 脈衝聲波源)來實行時,可進一步利用一般離子技術進行 離子化。一種此類離子化技術係利用一電子槍產生一電子 束並導引至分子以產生帶電荷分子,其他使樣品分子帶電 荷的方法包含使用可產生碰撞程序或光離子化程序的裝 置、可產生光子誘發電荷轉移的裝置、可產生電子貼附離 子化技術的裝置、可產生離子貼附離子化技術的裝置等。 在部分實施態樣中,聲波輻射本身造成樣品中的分子變成 離子狀態。樣品105之分子的離子化可在進行施用聲波能 量以脫附分子之前、過程中或之後。 回到第一圖中,被脫附的帶電荷粒子被導引至質譜量 測與偵測設備119中之QIT 102。QIT 102可為任何市售之 QIT質譜分析器,例如:Jordan C-1251 QIT。QIT 102商品 藉由包含環狀電極128與末端罩狀(end-cap)電極127a與 127b數個電極形成的三維四極電場捕捉帶電荷分子進入一 振盪執道(oscillatory trajectory)。導引帶電荷分子進入阱 中的額外運動係依據施加電壓、驅動頻率及被捕捉分子特 有的質荷比數值(儘管係以單一分子或粒子為參考,但可 理解的是QIT 102内部可具有多過一個的分子)。因此,當 玎明顯知悉如下··一被捕捉之帶電荷分子的質荷比可基於 14 1292822 其運動及QIT施加的電壓與驅動頻率來偵測。 被脫附的樣品分子可由環狀及末端罩狀電極間的缺口 或由環狀電極的孔中導入阱中。為確保帶電荷分子進入qIT 後保持在其中,一緩衝氣體在帶電荷分子通過QIT 1〇2時將 ▼笔荷分子之運動減緩。一種此緩衝氣體的代表係為氦 氣,其係使QIT 102内的壓力保持在大約1 mTorr。提供其 他類型的氣體及/或其他類似的減幅技術之減幅介質也可促 進QIT 102内部捕捉帶電荷分子。 參考第二圖,一旦一帶電荷分子15〇抵達qIT 1〇2,即 供應一交流電壓源120以於QIT 102内部創造出一電場來捕 捉該帶電荷分子150形成振盪運動。 由第二圖所示,交流電壓源12〇包含一驅動振盪器, 藉以產生具有一可調振幅及/或一可調頻率之電壓。舉例說 明,驅動振盪器122可為一合成功能產生器,藉以產生具 有在音頻及無線電頻路範圍内之頻率(即1〇〇 Hz-2M Hz) 之正弦曲線電壓訊號,以及可調之振幅程度。由驅動振盪 器122產生的電壓訊號可由一具處理器之元件自動控制。 由驅動振盪器122產生的訊號其頻率及振幅可額外的及/或 選擇性由使用者手動控制。 與驅動振盪器122連結的是一驅動變壓器126輸入終 細之功率放大器124 (power amplifier),具可調振幅與頻 率的電壓訊號1/^係因此在變壓器126之輸出終端產生。這 些輸出終端係與末端罩狀電極127&與127b連結。當可被理 解的是其他類型的電氣結構也可被用來在QIT 102内部,創 造出帶電荷分子150進行質譜分析所需之電場。例如為了 工292822 4頜外的電壓被施加於末端罩狀電極127&與1271?間以抵銷 、力^可提供用來在QIT内創造出電場之各種結構的描述, ,及刼作qit的描述,舉例,在美國專利號6,777,673,標 題為^隹子阱質譜儀,,的整份文件可特此併入參考文獻中。 士當帶電荷分子150被創造於QIT 102中的電場捕捉住 可QIT 102的驅動電壓之頻率係手動地或自動地調整,直 ,與QIT 102的共振狀態被建立。當其因此提供驅動電壓訊 唬之驅動頻率Ω與徑向頻率(即帶電荷分子與阱1〇2的 振盪頻率)之比係為一整數值w,且觀測到帶電荷分子的徑 p軌道形成一穩定圖案時。此一圖案係為嵌入於第一圖與 ,、圖中之生狀圖案。星狀圖案的分支數目η等於驅動電 壓頻率與離子化分子之徑向頻率的比,因此,在共振狀態 下,Ω =nc〇r 〇 、〜 在美國專利申請號11/134,616的文件中有更多詳細的 午,可被整份併入參考文獻中。這些被觀測到的特性,例 ^ =狀圖案分支的數目„與粒子的質荷比、頻率、以及驅 電壓的振幅相關,因此當獲得帶電荷分子150與QIT 102 的共振狀態時,可因此測得其質荷比m/Ze。 然而’因為有無限的m與Z組合會形成相同的m/ze ’因此m/Ze值本身並無法提供明確關於粒子15〇的質量 ^的資訊。所以有一種決定分子15〇質量的方法,就是讓相 :的分子150製造出不同的電荷狀態,因此相同的分子15〇 曰產生不同的m/Ze值。既然產生的那些m/Ze值的分子150 $ =仍然相同,則就有可能基於多數被生成的值與多 電荷狀態的相關性來決定出質量所。 16 1292822 為產生可於後續決定質量的分子15〇的多數的帶 狀態’可利用-附加電荷模組,暴—第― : 所示之電子槍⑽。電子搶⑽能由―例如熱鶴絲產生U 束放射,電子束被導引穿過—末端罩狀電極ma,咖其 :之-上的其中之-孔洞。電子束擊中分子i5G並誘發^ 子150在電何狀悲的改變。附加電荷模组係可 類型的可雜分子丨㈣同電荷㈣的元 门 附加電荷模組⑽的㈣可包含—產 j 之後在研究時導引贿射至分子。 件 一旦分子150的電荷狀態被改變後,在⑽搬 場控制而在徑向軌道移動的分+ 15〇冑失去 案。因此當分子軌道變得不彳塞t f〜 ° 壓訊號之_頻率重新調整驅動電 達到共振狀態。 +的新屯何“對應φΤΚ)2 為了將分子150的軌道圖案視覺化 QIT 102的驅動頻率以使粒子15〇 错此7捫登 宰,需使用-用來以❹Γ 相穩定的執道® 案而使用用末產生放射光的光源。當協調且單色的光, t ?雷射產生的光投影至粒子時,其可能可利用合適的 摘測益觀測到散射強度隨時間波動。因此,可觀測到一例 如分子15〇的粒子隨時間的運動。因此,如第一圖所示, -光源11G以協調單色光照射分子請。合適的光源係為雷 導子Λ射,分子150散射的光接著被光學鏡 』罨何耦合兀件照相機(charge coupled dev1Ce ’ CCD )之光子捕捉元件丨〗4。一 未顯示)#、減子敵元件114連結,散 1292822 射的光,因此顯示分子的徑向執道運動。根據顯示的執道 圖木^可刼作由電壓源120產生之驅動電壓訊號之驅動頻 =的調整。當顯示元件顯示一穩定執道圖案,則可觀測的 斗寸〖生例如知疋星狀圖案的分支數目則被紀錄並使用來確 定分子150的m/Ze值。 測到粒子150數個電荷狀態各自的m/Ze值後,分 ^ 5量值可利用例如描述於美國專利公開號i lm4,6i6 Ϊ 2單+地說,該程序反覆地為分子150製造的 (即指定)不同的質荷比值。該程序接 偏差的-系所獨立計算出咖 平均質旦=: 值’以及獨立計算其選出系列的 从二工里 支忖領域熟知此項技藝當可理解豆他由帶電 術也可被使用。 祕來_帶電荷分子質量的技 偵’則刀子15〇質量以及因此I監定該分子的@库可由 具處理器元件(圖未呈現)處理。此一d::: 含-電腦及/或其他類型之適合多種應用二處 此類7L件可包含暫時或非暫時記憶 - 出功能的周邊元件。此補、套开心入二及啟用輸入/輸 ^ ^ 頰周邊兀件包含例如CD-ROM槽及/ ,人’、:5網路連接係為了下載包含電腦摔作i兒明 以啟動具處理器元件之一般操作的 二 150質量的軟體工具程式。此-具處理器元件;

Description of the invention: [Technical field to which the invention pertains] More specifically for mass spectrometry, the present invention relates to mass spectrometry to produce gas phase charged molecules. [Prior Art] Mass spectrometry can be based on its mass-to-charge ratio (usually expressed in Saki or ▲), so it is necessary to investigate the charge molecular properties in an electric field when performing f-spectrum analysis. The nature of charged molecules can be judged by their mass to charge ratio. For example, in a quadrupole ion-trap mass spectrometer, charged molecules are trapped by an ion trap, and an applied electric field is applied to the trapped molecules to cause the molecules to operate in a manner, thereby indicating the mass-to-charge ratio (in w/ Name or representation). By detecting the mass-to-charge ratio of the captured molecule, the mass of the molecule can be detected, thereby identifying the molecule. In order to generate charged molecules for mass spectrometry, techniques commonly used to ionize molecules by mass spectrometry have been investigated, and charged molecules in at least a portion of the gas phase are provided. Techniques for ionization and generation of gas phase molecules have been explored, such as Matrix Assisted Laser Desorption Ionization (MALDI), which may cause matrix molecules in a sample to be introduced into a gas phase molecule. In addition, the ionization process often produces fragmentation and partial destruction of the target molecule. Performing an ionization procedure on the sample of the molecule often increases the complexity of the mass spectroscopic image.

In still another aspect, the method of fabricating a gas phase molecule of the present invention comprises: providing a sample of one molecule; and directing a sample of the acoustic wave to the molecule to desorb at least a portion of the molecule from the sample without the ionization procedure of the sample. . The at least partially desorbed molecule has a charge. The desorbed molecules were subjected to mass spectrometry. In still another aspect, the gas phase molecular device of the present invention comprises a container for accommodating a sample of one molecule; and an acoustic wave source configured to direct sound waves to the sample of the molecule to cause at least Some of the molecules are desorbed from the sample. The at least partially desorbed molecule has a charge. A 7 1292822 ^ spectrometer can be set up to analyze the aforementioned desorbed molecules. The aforementioned samples were not exposed to sonic radiation under an ionization procedure. The details of one or more implementations of the invention are set forth in the drawings. Other features, objects, and advantages of the invention are apparent from the following claims, claims and claims. [Embodiment] The first figure is a front view of an exemplary apparatus 1 using a mass spectrometer to analyze molecules that are desorbed by acoustic radiation (i.e., released from a sample provided). The second figure is a block diagram of the first figure device (for the purpose of the simplified drawing, some of the parts in the first figure are not shown in the second figure). As shown in the first and second figures, the device 10A includes an acoustic wave source 109 that directs sonic energy to a sample 忉5 of one molecule to desorb at least a portion of the molecules in the sample. The desorbed molecules thus form gas phase molecules which are analyzed by the mass spectrometry and detection device 119 of the device. It will be readily understood that the at least partially desorbed molecule has a charge and, further, in some embodiments, the charge distribution of the desorbed molecule is substantially the same as the charge distribution in sample 105. To produce a gas phase molecule, a container 105 containing a sample of molecules is required. The sample 105 of the molecule is placed in proximity to the mass spectrometer device 119 so that a portion of the molecules can be introduced into the mass spectrometer measurement and detection device U9 after being released. In the first figure, the sample is provided with a quadrupole ion trap 102 (the open end of the pipe or conduit of the Quadmpole Ion Trap (QIT) (not shown), thereby introducing the inner region 103 of the qIT 1〇2, the quadrupole ion trap The inner region 103 of 1〇2 is the point of mass spectrometry operation. 8 1292822 The acoustic radiation produced by the acoustic source 1G9 is then directed onto the sample 105 of the molecule. The molecules in the partial sample 105 then gain sufficient kinetic energy to enable The bulk of the sample 105 is desorbed or released. Those desorbed molecules are directed into the inner 1〇3 region of the QIT 102. The gas phase molecules that are mass spectrometrically analyzed by sonic light are generally not ionized. Any molecule that is reduced in supply will have at least some of the molecules already ionized' a this has a positive or negative charge (such molecules that do not have to pass the ionization process, ie, have a charge, sometimes called "day ^ (b_ -charge) Molecule. In fact, there is also the nature of the sample. It is considered that there is no knife to take the mouth and even the high-eight sons in the ionized sample, which makes the concentration of the charge molecules change extremely momentarily, but in all samples. : two have The sub-molecular system carries a charge. Therefore, any fraction that is provided has a unique charge distribution. The knife is in the mouth when the sound wave is applied to a sample of one molecule, and the sound is occluded, thus causing the molecule. From the laser-induced acoustic desorption in the sample (10) released ===, the induced wave (4) ^ disk vibration frequency is approximated by the acoustic wave induced range, therefore, the Ray (four) wave can effectively destroy the molecular table (10) junction. , ^ induces the consistency between the frequency of the acoustic wave and the vibration frequency of the surface bond, and the transmission of the energy can be avoided, thus avoiding the loss or failure of the energy conversion, which is born in the common technology of manufacturing gas phase molecules. Further, the sound wave ^ Hanging, the molecules are detached smoothly without splitting. In some implementations, the desorbed molecules of the sample I = have the same identity as the molecules in the sample. "The charge is divided into 9 1292822, although acoustic wave desorption is used without accompanying Any other ionization may only produce a small amount of gas phase molecules. However, for mass spectrometry purposes, even a small amount of charged gas is sufficient to form a gas phase because the mass spectrometer device requires only a small amount. Charged molecules are sufficient to identify the relative w々 values of these molecules. Although the ratio of charged ions to neutral molecules/particles is low, in some cases, the overall detection efficiency is comparable to that of mass spectrometers using ionization devices. Approximate, even better. Mass spectrometry of biomolecules or biological particles in mass spectrometers using ionization devices, the ionization rate is generally very low, for example when using MALDI or electrospray ionization (ESI) The ionization efficiency of biomolecules is generally lower than 0.0001. For some large biomolecules, the efficiency may be close to 0. For example, macroglycan molecules (M> 100,000 Daltons) cannot be ionized properly using a general ionization device. Furthermore, although the unbonded molecules are released into the gas phase smoke due to sonic desorption, the presence of uncharged molecules in the gas phase does not affect the mass spectrometry results because the uncharged molecules are not charged. The particle detector detects that, in addition, the uncharged molecules are not captured by the ion trap device. The sonic desorption described herein can be applied to any type of molecule, including: 1) liquid samples and amorphous materials that do not have sufficient gas pressure at the operating temperature of the mass spectrometer, these liquid and amorphous materials contain liquid crystals and ionic liquids. (ionic liquids); 2) an analyte captured by a solid state sample, such as nitrogen captured in a metal foil, 3) an adsorbate on the surface of the substrate, such as a free radical on a catalytic metal surface; 10 1292822 4) Molecules such as proteins, nucleic acid fragments, glycans, lipids, glycoproteins, hormones, oligonucleic acids and antibodies; 5) biomolecular complexes, such as DNA-protein complexes and protein-protein complexes; '6) organic Polymers such as polystyrene and polyethylene glycol; 7) nanoscale and micron-sized particles containing quantum dots and polystyrene particle volume standards; 8) clusters or aerosols on the surface, especially for environmental applications Micron/nanoparticles collected by the substrate; 9) organelles, such as chromosomes or granulocytes; 10) cells, such as viruses, bacteria and red blood cells; 11) mycoplasma; and 12) gold With inorganic Dando (Clusters), and particles. Other types of molecules can also be desorbed by sonication and provided in the mass spectrometric analysis of the present invention. Returning to the first and second figures, the acoustic wave source 109 is arranged to cause the sound waves of the molecules of the sample 105 to be desorbed by a laser-induced Acoustic Desorption (LIAD) technique #f. . As shown, acoustic source 109 includes an electromagnetic wave source, such as a pulsed ultraviolet laser 106, to provide energy for substrate 104 to induce acoustic waves within the substrate. A suitable pulsed ultraviolet laser 106 is a laser having a frequency twice that of Nd:YAG. The acoustic wave source 109 also includes a substrate 104 that is disposed on the surface of the substrate to approximate access to the opening of the QIT 102. The laser beam can be focused onto the substrate using a focusing mirror 107. The laser beam of 1 〇6 is directed to the side of the substrate where sample 105 is not disposed. Therefore, sample 1〇5 is not directly in contact with the laser beam 1292822, and it can thus be protected from damage caused by direct exposure to laser radiation. The second diagram is a schematic diagram of a molecular desorption procedure using laser-induced sonic desorption techniques. As shown, the laser beam 310 from the laser source 1〇6 strikes the surface 320 of the substrate 1〇4 provided with the sample 105, and it can be seen that the sample 105 is disposed not directly with the laser beam. 31〇 contact surface 322. The beam current (i.e., the laser energy density) due to the intensity of the laser is higher than the spalling threshold (i.e., the energy point at which the material absorbs the laser energy to successfully break the intermolecular bond of the material). The absorbed laser beam thus causes the bond of the substance to be arranged on the substrate to be destroyed. As shown in the inset of the first figure, it is a laser peeling point having a radius of approximately 1 mm on the surface 320 of the substrate 104. When the bond between the substance and the substrate 104 is broken, the resulting shock wave passes through the substrate until it reaches the surface 322. The energy of the penetrating wave is transmitted to at least a portion of the molecules in sample 1〇5. Thus, when the energy is obtained by the molecule, part of the molecules are desorbed from the main body of the sample 105. As further seen from the third figure, the fraction I that is partially removed contains a neutral molecule (presented by a white circle), and a part is desorbed, and a charged molecule (presented by a black circle). Only the charged molecules in the desorbed molecules are captured by the electric field of an ion trap mass spectrometer, and the neutral molecules are not affected by the electric field. Although not shown, a sonic transducer can be used to monitor the results of sound waves. For example, the sonic desorption procedure can be monitored. - In order to promote the generation of shock waves in the substrate, the substrate 104 is composed of a material having a peeling threshold lower than the laser intensity used. The & materials used as the substrate are used; other materials having suitable peeling thresholds or other properties that make them suitable for inducing shock wave properties in the material may be used. In some implementations (not shown) the acoustic source 109 comprises a particle beam generator (e.g., an electron beam). Particle beam induces acoustic waves in the substrate 12 1292822 Desorbs the sample 105. Taking a laser beam as an example, when the beam current exceeds the substrate peeling threshold, the particle beam causes damage to the material in the substrate by the radiation on the substrate. As a result, shock waves are generated in the substrate and penetrate the substrate. When the shock wave reaches the surface of the deposited sample, the shock wave desorbs at least some of the molecules. In some implementations (not shown), the acoustic source 1〇9 contains a piezoelectric element that causes mechanical shock. In these embodiments, a controller emits an electrical signal to the piezoelectric element, causing the piezoelectric element to mechanically displace the element based on the signal strength. The piezoelectric element is located near the opposite surface of the surface of the substrate deposited relative to the sample molecules. When the piezoelectric element is mechanically moved Z, it strikes the substrate or the substrate, thereby causing generation of sound waves or shock waves and penetrating the substrate. These penetrating waves reach the surface of the substrate where the molecular sample is deposited causing at least some of the molecules to be desorbed from the sample. Other types of components that can be activated to generate mechanical shock and transfer to the substrate can also be used. In some implementations, the acoustic wave generator can be used to generate acoustic waves that are projected directly onto the sample. Therefore, the generated sound waves do not need to penetrate other media, and the generation of sound waves does not pass through the incident beam (particle beam or beam) to induce an intermediate process of vibration waves in the substrate, or mechanical vibration is generated to create vibration in the substrate. In some implementations, the acoustic generator can be a continuous sonic source, an ultrasonic source, or a pulsed acoustic source. The resulting sound waves are then projected onto a molecular sample placed on a container or substrate. When a sound wave hits a sample, it transmits sonic energy to the molecule, with the result that at least some of the molecules gain sufficient kinetic energy to drive them out of the sample. At least partially desorbed molecules are charged molecules, so those molecules can be analyzed by mass spectrometry. In some embodiments, the desorbed molecule will thus have a substantially identical charge 13 1292822 distribution within the molecular sample 105. Although the use of sonication techniques described herein does not require ionization procedures to ionize molecular sample 105. In some cases, the ionization of the sample can still be carried out. For example, a larger amount of charged molecules are required in some examples. For example, when sonic desorption is performed by directly projecting incident acoustic energy into the sample 105 (e.g., using a continuous acoustic source, an ultrasonic source, and/or a pulsed acoustic source), ionization can be further performed using conventional ion techniques. One such ionization technique utilizes an electron gun to generate an electron beam and direct it to a molecule to produce charged molecules. Other methods of charging a sample molecule include the use of a device that produces a collision procedure or photoionization procedure that produces photons. A device for inducing charge transfer, a device capable of generating an electron attaching ionization technique, a device capable of generating an ion attached ionization technique, and the like. In some implementations, sonic radiation itself causes the molecules in the sample to become ionic. Ionization of the molecules of sample 105 can be performed before, during, or after application of sonic energy to desorb molecules. Returning to the first figure, the desorbed charged particles are directed to the QIT 102 in the mass spectrometry and detection device 119. The QIT 102 can be any commercially available QIT mass spectrometer, such as the Jordan C-1251 QIT. The QIT 102 commercial captures charged molecules into an oscillatory trajectory by a three-dimensional quadrupole electric field comprising a ring electrode 128 and a plurality of electrodes of end-cap electrodes 127a and 127b. The additional motion that directs the charged molecules into the trap depends on the applied voltage, the drive frequency, and the mass-to-charge ratio value specific to the captured molecule (although reference is made to a single molecule or particle, it is understood that there may be more inside the QIT 102) Pass one molecule). Therefore, it is apparent that the mass-to-charge ratio of a captured charged molecule can be detected based on the motion and the voltage applied by the QIT and the driving frequency of 14 1292822. The desorbed sample molecules can be introduced into the well from the gap between the annular and end cap electrodes or from the holes of the ring electrode. To ensure that the charged molecules remain in the qIT and remain there, a buffer gas slows the movement of the gun molecules as the charged molecules pass QIT 1〇2. One such buffer gas is represented by helium which maintains the pressure within the QIT 102 at about 1 mTorr. A moderating medium that provides other types of gas and/or other similar reduction techniques can also facilitate the capture of charged molecules within the QIT 102. Referring to the second figure, once a charged molecule 15 〇 reaches qIT 1〇2, an AC voltage source 120 is supplied to create an electric field inside the QIT 102 to capture the charged molecules 150 to form an oscillating motion. As shown in the second figure, the AC voltage source 12A includes a drive oscillator to generate a voltage having an adjustable amplitude and/or an adjustable frequency. For example, the drive oscillator 122 can be a composite function generator to generate a sinusoidal voltage signal having a frequency within the range of audio and radio frequencies (ie, 1 〇〇 Hz - 2 Hz), and an adjustable amplitude level. . The voltage signal generated by drive oscillator 122 can be automatically controlled by components of a processor. The frequency and amplitude of the signal generated by drive oscillator 122 can be additionally and/or selectively controlled manually by the user. Connected to the drive oscillator 122 is a drive transformer 126 that inputs a final power amplifier 124. The voltage signal 1/^ with adjustable amplitude and frequency is thus generated at the output terminal of the transformer 126. These output terminals are connected to the end cap electrodes 127 & 127b. It will be appreciated that other types of electrical structures can also be used within QIT 102 to create the electric field required for mass spectrometry of charged molecules 150. For example, in order to work 292822, the voltage outside the jaw is applied to the end cap electrode 127 & and 1271 to offset, the force can provide a description of the various structures used to create an electric field in the QIT, and the qit The entire document, which is described in U.S. Patent No. 6,777,673, the disclosure of which is incorporated herein by reference. The charge-carrying molecule 150 is created by the electric field created in the QIT 102. The frequency of the drive voltage of the QIT 102 is manually or automatically adjusted, and the resonance state with the QIT 102 is established. When it thus provides a driving voltage signal, the ratio of the driving frequency Ω to the radial frequency (ie, the charged molecule and the oscillation frequency of the well 1〇2) is an integer value w, and the formation of the path p of the charged molecule is observed. When a pattern is stabilized. This pattern is a green pattern embedded in the first figure and the figure. The number of branches η of the star-shaped pattern is equal to the ratio of the frequency of the driving voltage to the radial frequency of the ionized molecules, and therefore, in the resonance state, Ω = nc 〇 〇 , 〜 in the document of US Patent Application No. 11/134,616 More detailed noon can be incorporated into the reference in its entirety. These observed characteristics, the number of branching patterns of the pattern = are related to the mass-to-charge ratio of the particles, the frequency, and the amplitude of the driving voltage, so when the resonance state of the charged molecule 150 and the QIT 102 is obtained, it can be measured The mass-to-charge ratio m/Ze is obtained. However, 'because there are infinite m and Z combinations, the same m/ze will be formed. Therefore, the m/Ze value itself does not provide information on the quality of the particle 15〇. Therefore, there is a kind of information. The method of determining the mass of a molecule is to let the phase 150 of the phase produce different states of charge, so that the same molecule 15〇曰 produces different m/Ze values. Since the molecules of those m/Ze values are generated 150 $ = Still the same, it is possible to determine the mass based on the correlation between the majority of the generated values and the state of the multi-charge. 16 1292822 The state of the band that produces a majority of the molecules that can be subsequently determined by the mass 15 ' Module, Storm - No.: The electron gun (10) shown. The electronic grab (10) can generate U beam radiation from, for example, hot crane wire, and the electron beam is guided through the end cap electrode ma, on the - One of them - the hole. Hits the molecular i5G and induces a change in the electrical conductivity of the sub-150. The additional charge module is of the type of heterogeneous molecule (4) and the charge (4) of the elementary gate additional charge module (10) can be included - after the production During the study, the bribe was directed to the numerator. Once the charge state of the numerator 150 was changed, it was lost in the (10) shift control and moved in the radial orbital + 15 。. Therefore, when the molecular orbit became uncongested tf~ ° The frequency of the pressure signal re-adjusts the drive power to reach the resonance state. + The new geometry "corresponds to φ ΤΚ" 2 In order to visualize the orbital pattern of the molecule 150 to drive the frequency of the QIT 102, the particle 15 is wrong. Need to use - to use a source that produces a radiant light with a stable phase. When the coordinated and monochromatic light, the light produced by the t-ray is projected onto the particle, it may be possible to observe the scattering intensity fluctuating with time using a suitable sweeping benefit. Therefore, an example of the movement of particles such as molecules 15 随 over time can be observed. Therefore, as shown in the first figure, the light source 11G illuminates the molecules with coordinated monochromatic light. A suitable source of light is a ray-directed ray, and the light scattered by the numerator 150 is then optically mirrored by a photon capture element charge4 of a charge coupled dev1Ce ’ CCD. One does not show) #, minus the enemy element 114 is connected, scattered 1292822 light, thus showing the radial orbital motion of the molecule. According to the displayed trajectory, the driving frequency of the driving voltage signal generated by the voltage source 120 can be adjusted. When the display element displays a stable cue pattern, the number of branches of the observable cell, such as the known star-like pattern, is recorded and used to determine the m/Ze value of the molecule 150. After measuring the respective m/Ze values of the plurality of charge states of the particle 150, the value of the fraction can be manufactured for the molecule 150, for example, as described in U.S. Patent Publication No. lm4,6i6 Ϊ 2 (ie specify) different mass-to-charge ratio values. The program is independent of the calculation of the average quality of the denier =: value 'and the independent calculation of its selected series from the second division of the field of support is well known in the field.

This has a processor component; it is used to detect the quality of the molecule 150, and it is used to implement other functions. The quadrupole mass spectrometer shown in σ ^s ~ is only a 1292822-like mass spectrometer that can be used to detect mass spectrometry analysis of molecules 150 desorbed by sonic radiation in sample 105. Other types of mass spectrometers that are otherwise set up, such as different detection modules, can also be used. The Bayer-of-flight mass spectrometer is a domain type-type time-of-flight mass spectrometer that utilizes a drift zone field plus ball = time to resolve different masses between charged molecules. An electrical field, and Φ some from a ^ can enter an electric field-free drift zone, the second dioxin, the charge of the charged molecule and the v system is the applied voltage. Both the second kinetic energy system is equal to 2/2, and the lighter molecules will be heavier. Because of the :: and the faster detection of the amount of detection at the end of the drift zone, and because of =2: the special particle's time-of-flight detectable molecule Sun Yan described another combination with the sonic Korean program The qualitative statement is that the feather field type mass spectrometer is accelerated in this type of mass== electric field, and then an adjustable electric power is used: ΐ; ίί directional deflection in the tube. Only those with the same centrifugal force and centripetal; i force = (b) will not be detected. ί: The share was decided. Therefore, the mass of the charged molecule and = another mass spectrometer that can also be used is the Fourier movement. 19 1292822 The vortex-accelerated motion of the excited ionized molecule is then accepted by the cryo-plate. The magnetic domain signal is obtained when all the gyro-acceleration frequencies of the ionized molecules are detected. Next, the Fourier transform is performed on the time domain signal to obtain the frequency field image of the % field sfl, and the result of the Fourier transform is converted into a mass spectrum which can identify various charged molecules to be studied. Other types of mass spectrometers, including ion mobility mass spectrometer analysis and other types of ion trap negative oximeters, can also be used in conjunction with the sonic desorption techniques described herein. Detecting charged molecules for determining molecular mass-to-charge ratios may utilize suitable detectors and/or detection techniques, including charged particle elements having a second electron injection, such as microchannel plates, channel multipliers ( Ch heltr〇n) 5 Ge electron multiplying element (electr〇nm such as device), based on energy measurement of the debt detector, such as charge sensing components. Yu Bei! The changed _ device 'for example, the micro cantilever is similar to other plastic moldings. Some instruments, such as 'light scattering based detectors, are suitable for particle detection of M quadrupole ion trap mass spectrometers. Experiment: The effect of sonic desorption in a graph analysis uses a mass spectrometer device similar to the first bioparticle to analyze a single full-scale run wafer. The sample of the selected birch was placed on a semiconductor substrate (0.5 mm thick and one mixed * Μ sample was not placed in the matrix compound 〇 w (10) stone picking stone (10) YAG) laser beam projected onto the base back side) . 20 1292822 The field emission wavelength is 532 nm and its laser energy is approximately 3 每 per laser pulse + ^ since the laser beam is projected onto the back side of the substrate with the sample (ie the non-straight sample itself). The desorption procedure is primarily caused by laser light induced substrate formation. Next, the molecules desorbed from the sample are captured by a quadrupole ion trap. + An argon ion laser beam is used to illuminate the captured cells to produce scatter. The wavelength of the argon ion laser is 488 nm, and the laser energy is about ~1 〇〇. An optical lens is used to enhance the collection of scattered laser light, and then the photon detector of the CCD element is used. By adjusting the capture drive to obtain the resonance movement of the cells, the mass-to-charge ratio of the desorbed cells can be obtained. The mass of the desorbed molecules can be utilized to change the charge and state of the molecule, and is described in the United States. The patent application No. 11/134,616 patents the quality of the calculation of the numerator. The robbing is used to change the charged state of the molecules trapped in the QIT, except that the ionized or charged program is not applied to the molecule. Therefore, being guided to the dragon

The average mass m/Nc of the dehydrated E. coli cells detected as described in the fourth panel was 5.35 + 0.24 x 10 otox (Da). It can be seen that the water contains about 7〇~8〇% 1292822 before the bacteria are dehydrated. Therefore, this measurement data infers that the wet weight of the cells is ~0.35 Pg. Its lineage = = ~1 micron long x ~ 0 6 micron diameter) with density (~H g / cm3) to estimate the bacterial particles. Therefore, laser-induced sonic desorption can accurately determine the quality and identity of molecules (ie, E. coli cells). A similar mass spectrometry was performed using sonic desorption on polystyrene nanoparticles having a diameter of 0·269 ± 0·007 nm. The fifth graph is a graph showing the relationship between the number of particles induced by laser-induced sonic desorption and the detected quality of the polystyrene nanosphere community. As shown in the fifth graph, the average mass detected is 617 ± 0.18 x l09 Da, which is 6.5 ± 0.4 calculated from the straight, 0.369 μm and the subsequent value of 1.055 g/cm 3 using a single polystyrene nanoparticle. xl〇9Da is equivalent. The image of polystyrene particles produced by electron microscopy is embedded in the fifth image, and the scale of the embedded image is 300 nm. The six-figure system is used for laser-induced acoustic desorption by 〇·5 mm thick lithography wafer. A map of the state of charge of the particles released. The two samples that were measured were 0. 269 nm polystyrene nanoparticles (shown in the sixth panel area 61 )) and large intestine rod fine molecules (shown in region 620). As shown, for each of the polyethylene nanoparticles and E. coli molecules, the desorbed charged molecules introduced into the mass spectrometer have a symmetric distribution. The charge distribution of these charged molecules is not established using the procedures of molecular ionization of commercially available mass spectrometers. Nonetheless, as has been suggested, an ionization module can be used to charge a molecule desorbed by the sonication procedure of the present invention. The sixth figure shows that the sonic desorption procedure can provide natural charged molecules in the sample without the need to operate an additional ionization procedure.
