Abstract

Near infrared spectroscopy (NIR) analytical technique has been applied widely in the last ten yeas. VariousNIR instruments of different types and purposes have been emerged like bamboo shoots after a spring rain. The papersummarizes the main specifications and their evaluation methods of NIR instruments, such as resolution, wavelength accuracyand repeatability, photometric accuracy and repeatability, photometric noise, scanning speed, stray light, accessories, andsoftware functions. It is hopeful that it will be useful for customer to select and purchase an appropriate NIR instrument. Thepaper may also be taken as a valuable reference for manufacturer in the design and development of NIR instruments.
