AI Technical Summary

Problems solved by technology

[0008] To sum up, due to the complex optical system, the existence of the moving element and the fixed reference in the traditional molecular spectroscopy, the structure of the instrument is relatively complicated, and the volume is large, the linear range is narrow, and the signal loss is large, especially when the moving element is used. It leads to difficulties in model transplantation and model sharing, resulting in a large amount of data that cannot be shared and cannot generate higher value

Abstract

The invention provides a multisource spectrograph. The multisource spectrograph is provided with a case, a top cover, a charging port, a switch and a working indication lamp, wherein the case is internally provided with a data acquisition card, a cell grid, a quartz glass sheet and a sample pool in sequence from bottom to top; the data acquisition card is provided with a power supply management module, LED (Light Emitting Diode) light sources, photodiodes, a multi-path analogue switch, a programmable amplifier, an A / D (Analogue / Digital) conversion chip, an MCU (Micro-programmed Control Unit) microprocessor and wifi; each grid of the cell grid corresponds to one LED light source and one photodiode; an optical module is composed of the LED light sources and the photodiodes; and the top cover is arranged at the upper end of the sample pool. The multisource spectrograph takes a sample as a reference, and a series of reference signals are formed by changing a reference wavelength; the multisource spectrograph is low in manufacturing cost and utilization cost and is convenient to use; model sharing of different instruments can be realized, and values of big data can be sufficiently expressed; and the multisource spectrograph is a tool capable of providing effective spectrum analysis for Internet.

Description

technical field [0001] The invention relates to the technical field of analytical instruments, in particular, it belongs to analytical instruments for chemical component detection, and is a multi-source spectrometer. Background technique [0002] Spectroscopic analysis instruments are the most commonly used instruments for structural identification and quantitative analysis of chemical components, and are widely used in quantitative and qualitative analysis of chemical components in food, medicine, agricultural products, chemicals, materials and other fields. The theoretical basis of the spectrum analyzer is: different functional groups in chemical molecules have different responses to light of different wavelengths, by analyzing the difference between the incident spectrum (usually the absorption reflection spectrum formed by the reference reagent) and the response spectrum after the sample reacts Qualitative analysis such as structural identification and category determina...
