Problems solved by technology

[0006] It can be seen from the above that traditional spectral analysis methods rely on the calibration and modeling of each independently analyzed sample, which usually requires a large amount of chemical analysis and model calibration, and requires different analysis methods and modeling for each different sample method, so that its application requires a large number of professionals and time costs and cannot be widely used on a large scale

Description

technical field [0001] The invention belongs to the field of spectral analysis and detection, and in particular relates to a method for performing spectral analysis modeling based on artificial intelligence self-learning and mapping the chemical components of a target analyte. Background technique [0002] Both infrared absorption spectroscopy and Raman emission spectroscopy are spectral analysis techniques based on molecular vibration information of substances. Through the specific absorption of different molecules in different light bands, infrared absorption spectroscopy can provide information on the molecular components of substances. Through the specific emission of different wavelength bands produced by different molecules under excitation light, Raman spectroscopy can provide information on the molecular composition of substances. These two spectral analysis methods are widely used in production quality monitoring and hazardous substance detection due to their advan...
