ATR infrared spectrum human calculus analyzer

Abstract

The ATR infrared spectrum human calculus analyzer comprises an ATR infrared spectrometer shell connected with an external computer, and a light source, an interferometer, an ATR part, a detection amplification unit and a spectrum data AD acquisition and conversion unit are sequentially arranged in the ATR infrared spectrometer shell; wherein the ATR part comprises an ATR shell, a sample objective table is installed in the middle of the upper surface of the ATR shell, two film-coated ellipsoidal mirrors are installed below the sample objective table in the ATR shell, a plurality of film-coated reflectors are installed in a cavity of the ATR shell, a light inlet and a light outlet are formed in the two opposite side walls of the ATR shell respectively, an ejector pin material pressing part is arranged on the ATR shell, and the ejector pin material pressing part is arranged in the cavity of the ATR shell. One side of an inner cavity of the ATR shell communicates with an inflation inlet, and the other side of the inner cavity of the ATR shell communicates with an inflation outlet According to the ATR component top pressure mechanism design, sample pretreatment and continuous inflation structure design are not needed, interference of water and carbon dioxide in air is removed, and the accuracy of a test result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of an ATR infrared spectrum analysis device, in particular to an ATR infrared spectrum human stone analyzer. Background technique [0002] At present, the analysis of human stones mainly adopts the automatic analysis system of infrared spectroscopy to analyze the stone components through the tablet method. This method needs to use an external tablet machine to fully grind the human stones, and then mix a certain proportion of spectrally pure potassium bromide. Press the tablet, and then place the pressed tablet in the sample compartment of the automatic infrared spectrum analysis system for stones for automatic infrared spectrum analysis. This tableting method may change the microscopic state of the sample by grinding or squeezing the sample during the sample preparation process, which has a certain impact on the analysis results, and the tableting process is cumbersome, and the tablet thickness is too thick...

AI Technical Summary

Problems solved by technology

[0004] Although the analyzer provided by this utility model can make a certain analysis on the composition of stones, the sample needs to be cut flat or ground into powder, which requires a lot of pre-processing time, high processing precision, and requires operators to have super high pre-sample skills. Processing capacity, to cooperate with slicing or grinding equipment for pre-treatment sample preparation; even if the sample is pre-treated, it cannot ensure effective and full contact between the sample and the crystal, resulting in the depth of infrared light penetrating the sample is much smaller than the calculated value, resulting in reception The detector cannot collect effective infrared signals of sufficient intensity for analysis, and the noise is too large to directly affect the accuracy of the analysis
