Introduction This product is my company from a large number of domestic and foreign similar product advantage under the premise of independent research and development of the fast spectrum analysis instrument. It is a concentration of optical, mechanical and electrical products, algorithm technology fields, such as in a body's high technology integrated test instrument. It Is mainly composed of two parts of hardware and software, hardware, including: near infrared composition analyzer host, computer, printer, Software includes: PC software, the software of single chip processor and application analysis software and intelligent network management system. Working principle: near infrared spectrum of molecular vibration spectrum frequency doubling and frequency spectrum, is mainly due to the molecular vibration of non-resonant make molecules to high from the ground state energy level transition. Near infrared spectrum record is a single chemical bond in the molecular times the fundamental frequency of the vibration frequency and frequency information, it is often affected by hydrogen group X - H (C, N, O) X times and frequency of overlapping, within the scope of the near infrared spectrum, measure mainly hydrogen groups X - H times and frequency of vibration absorption.
