The application of eigenstructure tracking analysis (ETA) for the detection of an impurity under a chromatographic peak is discussed. A window of size three seems to be the most adequate for this problem. Some guidelines for interpretation of the ETA plots are given. A new normalization of spectra i

✦ Synopsis
The application of SIMPLISMA for the investigation of peak purity with liquid chromatography and diode array detection (LC-DAD) is proposed. SIMPLISMA is applied in the chromatographic direction, and is used to detect pure zones in the chromatogram. The performance of SIMPLISMA and of an approach based on the Gram-Schmidt orthogonalization technique are compared.
