Abstract
A near-infrared quantitative measurement instrument allows measurement in either reflectance or transmission modes depending upon a sample holder which is loaded in a sample chamber. The instrument has means for detecting in both the reflectance mode and the transmission mode, and the particular sample holder used determines in which mode the measurement is made.
