Creation Instructions (丨) Creation Field _ This creation is about a mass spectrometer device, and in particular A constant-time-of-flight mass spectrometer. Mass spectrometry is a very important physical and chemical analysis instrument that can accurately determine the mass of atoms or molecules. The basic principle is to convert the sample into gas phase ions in a vacuum, apply energy to make it move quickly, and then enter the mass analyzer, which can be separated and analyzed according to its mass to charge ratio (mass-to-charge ratio, m / e). To get k mass spectrum. Traditional mass spectrometers can be roughly divided into: magnetic field type (2) quadrupole type, and (3) time-of-flight, depending on the mass analyzer. TOF) and so on. Among them, magnetic field and quadrupole mass spectrometers obtain mass spectra by scanning magnetic or electric fields, because under a certain magnetic field or electric field, only ions with corresponding mass (mass-to-charge ratio) can pass through their mass analyzer. Measured by the detector, if the full mass spectrum must be scanned by the flower or the electric field: if the component disappears and the jsj tongue, y can not be obtained with a magnetic field or quadrupole mass spectrometer Temporary spectrum n. In contrast, the characteristic of a time-of-flight mass spectrometer is that all mass spectrometry data can be obtained at one time. The principle of a traditional time-of-flight mass spectrometer is briefly described below: The old_time-of-flight mass spectrometer is shown in Figure 1, including a constant kinetic energy ion source. The device (or ion generating and accelerating device) 11, ion drift device (or ion drift tube) 12 and ion detection (amplifier) 13 are three parts. 『Jin Yili House Flux Chamber Ion Source Device 11 Zonglili Electric House plus Jg ions make each ion have the same kinetic energy (¾ = eV) _, speed is different for different masses and 3 Standard (CNS) A4 (210X297 mm > --- (Please read the precautions on the back before filling this page) Order the Central Standards Bureau of the Ministry of Economic Affairs *: Printed by the Industrial and Consumer Cooperatives «. 3404twf.doc / 002 409933 c? _D7_ V. Creation instructions (>). If the ions are controlled to start flying at the same time, so that the ion-drift device 12 of the fixed-dose-drift zone is used, the time when ions of different masses reach the ions = detector 13 will also Different. Set the ion mass to m and the read load to + e: at the same time it is accelerated by V volts. Because the acceleration region is generally designed to be very short, the time required for the ion J1 to drift through the drift region L is: ti = W ^ That is, Li Wang Lan Fang Gen is directly proportional to _ ion detection ... Lai 13 Institute · Creation Description All the ions produced by the above-mentioned guardian spectrum · instrument ^ its away from the source ^ are all subjected to the electric field, the time of flight of this ion and its quality The square root of halo is positive ± ^. However, the source contains many different quality halo. From Liren avoid, the time separation ability will be ashamed when the mass is large and the time is not wide; that is, static, the difference in flight time between the same mass difference. X, tf, mass ion is greater than #, and larger If the mass ion is free, the chasing phoenix is small. If there can be a way to make each ion have the same momentum instead of kinetic energy, then the mass of the ion time of flight can be obtained. 1; in other words In other words, no matter what the mass of the chicks is, the time separation between the tomb mmi and the mass of the tomb can be as high as possible. There are many advantages in eyebrow analysis. It is easy to identify, but it is difficult to distinguish the heavy masses. From the above, those who use this special constant momentum ion source device to obtain mass spectrum in time-of-flight mode are called constant momentum.

Creation note (Γ) ti, when _ ”is plugged, it is named: P1 = j0'F (t) dt = J〇'eE (t) dt. So each ion will have the same momentum ΠM and It has nothing to do with mass; here we call the ion source of this creation a constant momentum ion source device 21; we can compare the ion source of a traditional time-of-flight mass spectrometer, as shown in Figure 1, because all its ions pass through the acceleration zone, so All ions get the same kinetic energy, that is, B = eV, so this traditional ion source can be called a constant kinetic energy ion source device. There are several ways to # 生 Uniform and other Xia field 乂 (1) Apply voltage to two Large parallel metal plates, the two metal plates will have a uniform equal electric field; (2) a voltage is applied to the thin metal plates 31 with circular holes arranged at equal intervals, and the potential differences between all adjacent two metal plates are equal Then, the circular hole channel 32 will have a uniform equal electric field region, as shown in FIG. 3; (3) a uniform resistance film 42 is plated or coated on the inner wall of the insulated circular or square tube 41, and here The two ends of the resistance film are connected with a metal foil or a thin metal chip. When it is on, a uniform isoelectric field will be formed in the tube, as shown in Figure 4. Now calculate the ion time of flight in a fixed-momentum time-of-flight mass spectrometer: assuming the ion mass is m and the initial velocity and position are 0, its acceleration a (t) in a uniform isoelectric field is: a (t) = ffi = eE (〇mm The speed after the end of the pulse (t = ti) is:
