Abstract

Fourier Transform Infrared has long been used to detect very subtle differences in chemical composition. Such deviations can also be used to assess product quality. Recent developments in sample preparation techniques make FTIR a practical QA system. However, ascertaining when a particular lot is within acceptable bounds can be very difficult. Discriminant analysis has proven a very effective method when coupled with traditional chemometric process control. Together with FTIR, they form a powerful quality assurance technique.
