针对油墨中三环及以上芳烃矿物油(3P-MOAH)检测方法缺失及基质干扰严重的问题,该研究提出一种基于多步净化与液相色谱-气相色谱-氢火焰离子化检测器联用的定量分析方法。通过溶剂提取、硅胶柱和氨基柱净化技术,有效去除油墨中烷烃矿物油、1~2环芳烃矿物油及烯烃干扰组分。优化后的氨基柱梯度洗脱程序(正己烷/二氯甲烷体系)实现了3P-MOAH的在线分离。方法学考察结果表明,定量下限达1.0 mg/kg,回收率为82.3%~109%,相对标准偏差(RSD)为7.6%~9.7%。该研究为油墨中三环及以上芳烃矿物油的定量检测提供了实用化解决方案,可为油墨及食品接触材料安全评估提供可靠的分析工具。
Addressing the challenges of the lack of detection methods and severe matrix interference for mineral oil aromatic hydrocarbons with three or more rings(3P-MOAH) in printing inks,this study developed a quantitative analytical method based on multi-stage purification coupled with liquid chromatography-gas chromatography-hydrogen flame ionization detection. Through solvent extraction,silica gel column and amino column purification technology,mineral oil saturated hydrocarbons,1-2 ring mineral oil aromatic hydrocarbons and olefin interfering components in the ink are effectively removed. An optimiz
ed gradient elution program(
n
-hexane/dichloromethane system) on the amino column achieved online separation of three or more rings in mineral oil aromatic hydrocarbons. The methodological investigation results indicated that the quantification limit reached 1.0 mg/kg,and the recoveries ranged from 82.3% to 109% with RSD ranged from 7.6% to 9.7%. This research provides a practical solution for the quantitative detection of three or more rings in mineral oil aromatic hydrocarbons in printing inks. The findings offer a reliable analytical tool for the safety assessment of printing inks and food contact materials.
