Combined chemical spectral detection system

Abstract

The invention discloses a spectro-detecting system, which is characterized by the following: realizing synchronous multi-group detection for multiple samples in the composite sample library through different frequency optical sources; containing variable frequency or utility serial filtrate light source, detecting plate with M*N transmission sample pools (M and N is between 2 and 100 or more) and high-resolution CCD digital detector for device (as picture displays); detecting transmission information through high-resolution CCD digital camera; calculating the density of specific material in kinds of samples according to background and data through self-designed software; analyzing quantatively for hundreds of samples within several seconds for combined chemical samples.

Description

Technical field [0001] The invention relates to a spectroscopic detection system that utilizes the characteristics of a substance having a specific absorption frequency in the ultraviolet and visible light regions and analyzes hundreds of organic or inorganic samples at the same time, and is particularly suitable for the analysis of a combined chemical sample Library. Background technique [0002] The characteristic of combinatorial chemistry is that it can synthesize a large number of samples in a short time and conduct rapid detection. Whether it has the ability to analyze a large number of samples and process massive data at the same time is the key to the success or failure of combinatorial chemistry research. Product characterization and quantitative analysis are often the bottleneck of combinatorial chemistry. [0003] In combinatorial catalysis research, a multi-channel gas chromatography (GC) detection system was designed for product analysis (Thomas N. Corso et al., US 6...

This method has the following disadvantages: 1) Since many chemical reactions have thermal effects, it is impossible to determine what products are generated; 2) The products and products on the catalyst sample plate diffuse with each other, and the products will also react and release heat on other samples; 3) Due to the different composition of solid catalytic materials, even at the same temperature, the infrared radiation intensity will be different, resulting in noise, and the background noise is very strong

Its working principle is to use a chemical reagent to react with an analyte to generate a fluorescent substance, and then generate fluorescence under the action of ultraviolet light, and collect data using fluorescence imaging, which effectively extends the Edward S . The scope of application of the fluorescence imaging method developed by Yeung, but it still cannot analyze those compounds that cannot generate fluorescent substances through chemical reactions, and its application scope is small
