摘　　要：目的—开展包装印刷材料中全氟烷基化合物检测方法的探索研究。方法—基于液相色谱——串联质谱法,系统研究了建立方法的关键点对色谱图峰形以及标准曲线相关系数的影响,开发了全氟烷基化合物检测的液相色谱——串联质谱法。结果—1)C18 RRHD作为检测用色谱柱可获得良好峰形以及较短的检测时间。2)选择甲醇:乙酸铵-水体系为流动相,能有效延长色谱柱的使用寿命,同时保持出峰时间的稳定性、出峰效果的良好性。3)选择10μL作为检测进样量可以减少溶剂效应,改善峰形。在上述优化条件下,色谱峰形较为对称,检测时间控制在18 min以内,所有研究物质的相关系数均在0.99以上。该研究有望为包装印刷材料中全氟烷基化合物检测提供技术保障。In this paper,an exploration and research on the determination method of perfluoroalkyl compounds in packaging and printing materials was carried out.Based on liquid chromatographytandem mass spectrometry,the key points of the method were systematically studied.The results indicated that 1)Taking into account the detection time and the separation effect and peak shape of the chromatographic peaks,a chromatographic column of C18 RRHD 1.8μm×2.1 mm×100 mm was selected as the detection column.2)Selecting the system of Methanol:Ammonium Acetate-Water as the mobile phase can not only effectively prolong the service life of the chromatographic column,but maintain the stability of the peak time and the goodness of the peak effect.3)The detection injection volume of 10μL was chosen to reduce solvent effects and improve peak shape.Under the above optimized conditions,the chromatographic peak shape is relatively symmetrical,the detection time is controlled within 18 min,and the correlation coefficients of all substances are above 0.99.This research is expected to provide technical support for the detection of perfluoroalkyl compounds in packaging and printing materials.
