Abstract

The paper shows the expediency and effectiveness of using the chemometric methods in solving the problems offorensic identification at the level of establishing the common group affiliation. The paper gives illustrations of using the principal components method and cluster analysis in a comparative study of 19 samples of gas condensate according to gas-liquid chromatography data. The method of principal components is more obvious in its visual estimation as well as in grouping the objects having similar indicators of their component composition. The cluster analysis allowed to distribute the examined objects into groups from the beginning. This was confi rmed during their subsequent pairwise comparison by using the method of "fingerprints".
