Abstract
Last decade's advances and modern aspects of near infrared spectroscopy are critically
examined and reviewed. Innovative instrumentation, highlighted by portable and imaging
instruments, chemometrics data multivariate processing, and new and valuable applications
are presented and discussed. Because of these advances, this mature analytical technique
is continually experiencing renewed interest. The drawbacks and misuses of the technique
and its supporting mathematical tools are also addressed. The principal achievements
in the field are shown in a critical manner, in order to understand why the technique
has found intensive application in the most diverse and modern areas of analytical
importance during the last ten years.
