Description
Technical field
The invention belongs to analysis test equipment manufactures field, required concentric circles in more particularly, to a kind of infrared sample preparation
Piece puncher.
Background technology
Infrared spectrum is a kind of molecular spectrum, can be used to study the structure of organic molecule, functional-analytical group and is used for
Differentiate chemical species.Examination of infrared spectrum is not only applied very wide, and for many related disciplines, such as in chemical analysis subject
Oil, coal, medicine, geology, environment, meteorology, space science etc. suffer from important application.
When carrying out infrared test to pressed powder, commonly used method for making sample is pellet technique, typically infrared
Measure compressing tablet be diameter 13mm, thickness about 1mm about transparent disc.The process of infrared compressing tablet is: takes about 1-2mg sample
It is sufficiently mixed in agate mortar with 100-200mg KBr and grinds, and ground mixture is put in mould, then will
Mould is put in forcing press, in 10t/cm2Under the pressure of left and right, 1-2 minute can get transparent or uniform translucent ingot piece.
But this method for making sample can run into two problems in actual sample making course: first, the sample size of use is big, needs
Want 1-2mg, and miniature compression mold is more rare and thin slice that extrude is not transparent；Second, by transparent thin slice from mould
Frangible when taking out in tool, not easy to operate.In order to solve this problem, we attempt for the scraps of paper of impermeable infrared light being cut into one directly
Footpath is the disk of 13mm, and a circular hole made a call to by centre puncher, and Circularhole diameter is about 6mm, and this round scraps of paper with holes is first put
On bed die, then the mixture of sample and KBr is put in the hole of centre.The transparent sheet being pressed into just has been attached to round
The center of the scraps of paper, thus greatlys save the usage amount of sample, so that compressing tablet is more prone to take and preserve.But due to reality
When testing, the required scraps of paper are manual prepared, and the position of circular paper diameter and center hole is all very random, in the middle of the round scraps of paper
The deviation of center of circular hole can cause discontinuity, and the translucent half of gained compressing tablet one is opaque, affects the sample preparation of infrared sample
Success rate；It is desirable that the strongest part of the center of infrared beam i.e. infrared light can pass through the center of sample in experiment, this
All product are maximum with infrared light exposure, and infrared signal is just stronger, and the center of scraps of paper medial small hole often is offset from positive middle position
Put, this causes difficulty so that infrared beam center is misaligned with sample center for the focusing of hot spot during test sample, causes sample
Product infrared spectrum quality has declined；In addition, the round scraps of paper are cylindrical forming for manual shearing, it is difficult when excircle dimension is bigger than normal to put
Enter mould, the scraps of paper in a mold are placed out-of-flatness and also resulted in sample discontinuity after pressurization so that the compressing tablet one at center
Translucent one is semi-opaque；When scraps of paper excircle dimension is less than normal, in center hole, during tiling sample, the scraps of paper can rock back and forth
Bring inconvenience for sample preparation.
Therefore, the purpose of the present invention is to develop the concentric puncher that a kind of infrared spectrometer needs, and can quickly obtain
The smooth concentric circles scraps of paper of cylindrical otch.The thereby concentric circles scraps of paper, the compressing tablet of solid sample would be much more convenient, infrared beam poly-
Jiao will be more accurate, and while saving sample, save the sample preparation time, obtain high-quality infrared spectrum.
Content of the invention

Fig. 3 a is the concentric disk being obtained using the infrared concentric disk puncher of the present invention, and Fig. 3 b is to be obtained based on the present invention
Concentric disk, put into the schematic diagram after support with the infrared compressing tablet of gained after pressing potassium bromide troche, permissible from Fig. 3 a and Fig. 3 b
See, the concentric disk otch that the present invention is obtained is smooth, outer circular shape and center circle position are fixed and easy and simple to handle.Fig. 4 a is to make
The disk being obtained with prior art, Fig. 4 b is to put into the schematic diagram after support based on the disk that prior art is obtained, and uses KBr
The infrared compressing tablet of gained after compressing tablet, the preparation process of prior art mid-infrared disk is: is first extruded on the scraps of paper with circular die
One circular chapter, then uses puncher in scraps of paper central punch, finally cuts the scraps of paper with scissors along the shape of circular chapter.So
Prepared scraps of paper shape and center hole position are all very random, and complex manufacturing process, and the time of needs is more.
Fig. 5 a is the not infrared spectrum using disk sample preparation gained, and Fig. 5 b is the concentric disk system being obtained using prior art
The infrared spectrum of sample gained, Fig. 5 c is the infrared spectrum of the concentric disk sample preparation gained being obtained using the present invention.As Fig. 5 a and figure
Shown in 5b, the infrared spectrum being obtained using existing disk sample preparation, compared with the infrared spectrum not obtained using disk sample preparation, is made an uproar
Sound substantially becomes big, therefore can cause deleterious effect to spectrogram using existing disk sample preparation；As shown in Fig. 5 a and Fig. 5 c, use
The concentric disk sample preparation gained spectrogram that the present invention is obtained with not using disk sample preparation gained spectrogram very nearly the same it can be seen that use
Disk sample preparation with one heart has no impact to spectrogram quality.
The present invention has the following advantages compared to existing technology:
1st, concentric disk puncher can once be obtained a donut, formed infrared test in the urgent need to concentric circles
Piece, and ensure that concentric disk neat in edge and size is homogeneous, and puncher of the prior art also needs to after having beaten a hole
Cut cylindrical with scissors, cylindrical size and center circle position at random and take more；
2nd, discontinuity during compressing tablet, gained compressing tablet half are caused because round scraps of paper center of circular hole deviates before solving
The opaque problem of transparent half, improves the success rate of infrared compressing tablet；
3rd, enable infrared light spot accurately from the round scraps of paper centrally through solving asking of exact focus during infrared survey
Topic, improves spectrogram quality.
Particular embodiments described above, has carried out detailed further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail bright, be should be understood that the specific embodiment that the foregoing is only the present invention, be not limited to the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement done etc., should be included in the guarantor of the present invention
Within the scope of shield.
