Description
Technical field
The utility model belongs to the chemical industry instrument field, specifically, especially relates to a kind of miniature pelleting press that is used for the circular dichroism spectrometer.
Background technology
Solid circles dichroscope spectrum is a kind of powerful measure of studying chipal compounds; It not only can provide the solution C D information that spectrum is difficult to obtain; More near the environment in the solid phase, and can important information be provided to further investigation chiral Recognition, spontaneous fractionation, reaction mechanism etc.In addition, another advantage of solid circles dichroscope spectrum is the sign that can be used for the indissoluble sample.Solid circular dichroism test method commonly used is a pressed disc method, promptly earlier sample is carried out compressing tablet with infrared sheeter, carries out the circular dichroism spectrum test then.Yet in infrared sheeter compressing tablet process, often occur the compressing tablet transparency inadequately, problem such as too thick, too thin, breakage, directly influence test effect, accuracy and the efficient of circular dichroism spectrum.
The utility model content
The purpose of the utility model is exactly will overcome with the infrared spectrum sheeter to carry out the defective that circular dichroism spectrum compressing tablet exists, and provides a kind of simple in structure, measured circular dichroism spectrometer of compressing tablet matter to use miniature pelleting press.
The technical scheme of the utility model is achieved in that and comprises the seat of honour, intermedium and following; Be respectively equipped with 1～2 cylindrical punch on one end face at the wherein said seat of honour and following the end face; Intermedium is provided with 1～2 inner via hole, and the intermedium both sides are provided with handle.
Above-mentioned a kind of miniature pelleting press that is used for the circular dichroism spectrometer; The cross-sectional diameter of described first cylindrical punch and the 3rd cylindrical punch is respectively 3～5mm; The cross-sectional diameter of second cylindrical punch and the 4th cylindrical punch is respectively 5～7mm, highly is 3～5mm.
Above-mentioned a kind of miniature pelleting press that is used for the circular dichroism spectrometer, said intermedium height is 6.5～10.5mm, and the cross-sectional diameter of first inner via hole is 3.2～5.2mm, and the cross-sectional diameter of second inner via hole is 5.2～7.2mm.
After the utility model adopted said structure, convenient to operation, whole compressing tablet process was no more than 3min, and sample strip need not to take off, can be directly and intermedium be used for together testing; Required sample size is few; In conjunction with the little characteristics of circular dichroism spectrometer facula area; The cross-sectional diameter of the seat of honour, following cylindrical punch that is provided with is reduced into 3～5mm and 5～7mm, can sample size be reduced to 0.1 milligram, not only can the tested object of solid circles dichroscope spectrum be extended to micro sample; Can survey the CD spectrum of single crystal, and reduce the pollution of chemicals environment; The compressing tablet quality is good, and is big with equal pressure pressure after the cylindrical punch reduced cross-sectional area, and the transparency of compressing tablet is high, and yield rate is high.The utility model can be provided with the inner via hole in 2 different apertures, can realize once suppressing two coupons that vary in size.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model.
