This study demonstrates a method to quantitatively measure the oleophobicities of food packaging paper via using a tracer‐assisted headspace gas chromatography by adding a 40‐μL droplet of toluene‐doped oil onto a sample surface, wherein toluene behaves as volatile tracer. After 20 s, the sample was turned vertically to remove the oil and placed in a headspace vial. The amount of toluene in the residual oil adhered to the sample surface was quantified using headspace gas chromatography under full‐evaporation conditions. The results exhibit satisfactory precision (RSDs < 2.5%) and provide quantitative information on oleophobicity. The proposed method is simple, efficient and suitable for batch sample testing.

顶空气相色谱技术定量测定食品包装纸的疏油性

这项研究证明了一种通过使用示踪剂辅助顶空气相色谱法定量测量食品包装纸的疏油性的方法，该方法是在样品表面上添加40μL的甲苯掺杂油滴，其中甲苯表现为挥发性示踪剂。20秒钟后，将样品垂直旋转以除去油，然后将其放在顶空样品瓶中。使用顶空气相色谱法在全蒸发条件下定量分析残留在样品表面的残油中的甲苯含量。结果显示出令人满意的精度（RSDs <2.5％），并提供了有关疏油性的定量信息。所提出的方法简单，高效，适用于批量样品测试。
