A rapid non-destructive sampling technique for the analysis of volatile organic compounds (VOCs) emitted by paper sheets is described. A capillary, which is connected to a microcolumn packed with Tenax TA, is inserted between two sheets at the centre of a paper stack encapsulated inside a PET/Al/PE composite foil. The other end of the microcolumn is connected to a gas-tight syringe and an appropriate volume of gaseous phase is aspirated. The microcolumn is then thermally desorbed in a modified GC inlet (modification is presented) and analysed by gas chromatography-mass spectrometry (GC-MS). In the chromatogram from the analysis of artificially aged paper sample 21 compounds were identified. Advantages of the method including the short sampling time (1 min), simplicity and economic aspect are discussed.
一种用于分析纸张挥发有机化合物（VOCs）的快速非破坏性采样技术被描述。一个毛细管被插入到两张纸之间的中心位置，该毛细管与填充有 Tenax TA 的微柱相连，而这两张纸被封装在一个 PET/Al/PE 复合箔中。微柱的另一端与一个气密注射器相连，然后吸入一定体积的气相。微柱随后在一个改良的 GC 进样口（介绍了改良）中热解吸，并通过气相色谱-质谱联用仪（GC-MS）进行分析。在对人工老化纸张样品的分析中，在色谱图中鉴定出 21 种化合物。讨论了该方法的优点，包括采样时间短（1 分钟）、简单和经济方面。
