The rapid and simple analysis of protein samples without laborious pretreatments was studied by using pyrolysis gas chromatography (PGC). At first, correlations of the composition ratio of amino acid residues and peak intensity of their degradation products were investigated by PGC of simple protein samples whose composition of aminio acid were known. In 13 amino acids, it was possible to determine the composition ratio of amino acid residue in the protein with the peak intensities of their degradation products. This method was carried out in several protein samples (wool etc.), in which the results were similar to the reported values. In addition, the present method was possible to discriminate the protein species with the combused residues of protein samples or these proteins contained in KBr disk for infrared spectrometry. This method described in this report was useful for the identification of these protein samples in forensic chemistry.
