A primary characteristic of diffuse reflectance spectroscopy is fast and non-destructive determination of constituent concentration in products. The main goal is to find the nature of absorption (depending of wave length) and compare it with stable standard. NIR spectroscopy is a technology based on real number of molecules of each constituent and represents highly applicable analytical method. After calibration development or calibration transfer from one to another NIR instrument, it is necessary to verify the slope and bias of calibration. Results from multi year experiments show bias changes, while slope was constant, implicating that calibration changes had translator nature.
