Modern spectral analysis technology empowered by chemometrics:Theory,instrument and application progress
In recent years,the integration of modern spectroscopic analysis technologies with development characteristics of the times(such as artificial intelligence,big data,cloud computing and the internet of things)is closer and closer,and it has been widely used in various fields including agriculture,food,petro-chemicals,petrochemical engineering,metallurgy and geology.Some large-scale application achievements have been obtained in several fields,which makes a contribution to the development of technology and e-conomy.This paper mainly introduces the constitution and characteristics of modern spectroscopic analysis technologies integrated with chemometrics,and summarizes the chemometric methodologies and advance-ments employed for quantitative and qualitative analysis in spectroscopy.Based on some representative in-stances,the application status of modern spectroscopic analysis technologies in various fields were intro-duced according to the application scenarios,for example,the laboratory high-throughput analysis scenarios such as rapid crude oil evaluation,grain sorting and port iron ore classification;on-site rapid analysis sce-narios such as soil detection,mineral exploration,fruit picking assessment,and forensic identification;the industrial on-line analysis scenarios such as gasoline blending,smelting process material analysis,on-line coal quality analysis,and waste plastic classification.In the future,grounded in the miniaturization of spec-trometers,in-depth exploration of new spectroscopic theories,and the profound amalgamation of deep learning algorithms with spectroscopic technology,the rapid developments in precision agriculture,smart facto-ries,precision medicine,and intelligent environmental protection will offer robust impetus for the progressive evolu-tion of modern spectroscopic analysis technologies,thus heralding further innovations and advancements.
