We tested the performance of pyrolysis-comprehensive two-dimensional gas chromatography/mass spectrometry in the course of our cultural heritage studies, and compared its potentialities for the characterization of traditional East Asian handmade papers with those previously obtained by pyrolysis-gas chromatography/mass spectrometry. The evaluation of the two methods was conducted in considering the number of detected peaks, the compounds separation, the sensitivity, and the identification of marker compounds. The results showed that the number of plant markers (triterpenes and phytosterols) detected in a Japanese kozo reference paper was improved in the pyrolysis fingerprint. With a gain in sensitivity in the order of six, the case study of a museum sample confirmed that pyrolysis-comprehensive two-dimensional gas chromatography/mass spectrometry is more efficient for a reliable identification of museum collections samples and/or archaeological samples where tiny quantities of materials are the rule. The present study has been successful in refining a micro-destructive method based on analytical pyrolysis for the characterization of traditional East Asian handmade papers using pyrolysis-comprehensive two-dimensional gas chromatography/mass spectrometry.
