Abstract: |
In recent years,near infrared spectroscopic technology has been developed rapidly,which could be directly applied to the qualitative or quantitative analysis of various complex mixtures such as gas,liquid and solid.It has the advantages of rapid analysis,high efficiency,non-destructive and on-line analysis,and plays a more and more important role in scientific research,industrial and agricultural production.Meanwhile,miniaturization of near infrared spectrophotometer is an important development direction.Recently,there have been some different types of commercial miniatured near infrared spectroscopic instruments based on Micro Electro Mechanical System and Micro Opto Electro Mechanical System.Handheld or portable on-site rapid analysis is a more economical,efficient and flexible method.It has the advantages of small volume,low power consumption,low cost and convenient secondary development.It has been widely studied and applied in many fields such as agriculture,food,medicine,petrochemical industry and forensic science.The rise of Internet of things technology in many fields such as intelligent agriculture,intelligent factory,intelligent medical treatment and smart city has become the main force to promote the development of near infrared spectrometer towards miniaturization.This paper summarizes the commercialized miniaturized(portable,handheld and pocket) near infrared spectroscopy instruments and their application progress,and prospects the development trend and future applications of this technology. |
