“…The ion intensities were normalized to the sample mass and to the intensity of the 38 Ar isotope of the carrier gas. Table 2 shows the characteristics of the conventional and modified E. globulus kraft pulps with LMS(E) delignification, carried out under the reaction conditions optimized earlier [33]. The delignification extent, measured by the kappa number, is in the range of 42-43%, which is in accordance with published data [3].…”

“…The corresponding attribution of the pyrolytic products issued from cellulose pyrolysis is presented in Table S1. Identification of these products is supported by previous studies conducted on wood samples and pure cellulose samples pyrolysis (Faix et al 1991a, b;Pouwels et al 1989;Oudia et al 2009;Patwardhan et al 2009;Patwardhan et al 2011) and confirmed by comparison of their mass spectra with those recorded in the NIST database. No clear differences could be obtained between the reference papers from the compounds characterized in this region, even if some aromatics derivatives (compounds 74, 79) were detected more specifically for the mitsumata and gampi papers, but with relatively small intensities.…”

We report a pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) method capable of analyzing traditional East Asian papers. The method proposed is based on rapid and easy single step Py-GC/MS analysis that can be carried out with a minimum amount of matter, in the few microgram range. Three reference papers manufactured from kozo (Broussonetia kazinoki Siebold & Zucc.), mitsumata (Edgeworthia chrysantha Lindl.), and gampi (Wikstroemia sikokiana Franch. & Sav.) with the traditional hand paper making processes were examined. The method allows discrimination between terpenic and steroid compounds, which were revealed as chemical markers of origin of the plant fibers. Each paper investigated was found to have characteristic pyrolysis fingerprints that were unique to the traditional handmade paper, demonstrating the potential for differentiation of these biochemical components of fiber plants on East Asian papers towards identification and conservation of cultural heritage. The investigation on Py-GC/MS was extended to liquid extraction followed by GC/MS analysis to characterize the biochemical components of fiber plants. The main contribution of this study is to provide molecular criteria for discriminating plant species used for traditional East Asian hand papermaking. Py-GC/MS complements efficiently microscope identification especially for adverse cases. A case study of archaeological Chinese paper painting artefacts was thereafter successfully investigated to address informative potential and efficiency of the criteria of identification on ancient and degraded East Asian paperworks.

“…These bonds strongly influence the chemical reactivity and solubility of cellulose. As a result, cellulose is virtually insoluble in most common solvents, and the successful preparation of derivatives requires a special approach [27]. The production of regenerated cellulose materials is based largely on the old viscose method in which fibres and films are produced via soluble cellulose derivative, cellulose xanthogenate.…”
