摘要 建立了高分辨热裂解-气相色谱-质谱联用法(PGC-MS)鉴定虫胶漆中主要组分方法。水性虫胶漆样品烘干除去水份后得到的残渣置于裂解器中于600℃裂解6 s,裂解产物使用气相色谱分离、质谱鉴定。发现虫胶主要生成低碳烯烃、低碳芳烃、长链脂肪酸和长链脂肪烃等组分。该方法操作简便、快捷、实用,适用于虫胶漆的仲裁分析。 The method of a high-resolution pyrolysis-gas chromatography - mass spectrometry (PGC-MS) to identify the major components of shellac was established. Aqueous shellac samples after drying to remove residues of water was placed at 600℃ cracker cracking 6 s, cleavage products were separated by gas chromatographic and mass spectrometry identification. The main discovery shellac light olefins, aromatics, low carbon and long chain fatty acids and long chain fatty hydrocarbon component. The method is simple, fast, practical and applicable to the analysis of the shellac.
