This application note demonstrates the effectiveness of Agilent compact and portable FTIR systems for detecting counterfeit pharmaceuticals with three examples: ethambutol hydrochloride, cephuroxime axetil, and atorvastatin calcium.

This application note describes a very sensitive classification method, partial least squares–discriminant analysis (PLS-DA), incorporated in Agilent innovative MicroLab software, to classify and qualify materials of interest with greater sensitivity and specificity than possible with simple library search methods.
