Diffuse reflectance for a ground solid showing: (a) reflection from the cell cover; (b) specular reflection from the sample; (c) absorption and diffuse reflection from the sample; (d) total absorption by the sample. 1. 2. Conclusions While there is still the need for research on NIRS and the limits to its use, it is a useful technique. At present, NIRS works best on dried materials and requires constant checking to maintain the accuracy of calibration equations. JiaGang Page 12
Many questions still remain to be answered. there will be a steady increase in the demand for instrumental methods of analysis, such as NIRS. 1 2 3 1.8 y=a+bx, JiaGang Page 13
