Abstract: Chlorinated phenols were classified by the pattern recognition method PRIMA. For the purpose of the classification new characteristic features based on significant mass spectra losses were derived. Principal component analysis was used to present the separability of the selected classes. In the application of this approach there is no need for the spectral library and the spectra are interpreted much faster than by the library search methods. A reliability of the applied procedure for library spectra corresponded to 92 %. In the model mixture, 18 out of 21 substances were classified correctly.
