开发了一种可靠、灵敏且高效的方法，用于常规分析各种食用作物基质中的全氟辛烷磺酸 (PFOS) 和全氟己烷磺酸 (PFHxS)，包括谷物（谷物）、根类蔬菜（胡萝卜）、叶类蔬菜（生菜）和瓜类蔬菜（南瓜）。通过离子对方法提取目标分析物，然后进行固相萃取净化和 HPLC-MS/MS。对萃取溶剂的类型、净化柱和 Supelclean 石墨化碳的使用进行了评估，以达到优化的预处理程序。在开发的方法中使用相对于同位素标记内标的基质匹配标准校准以获得更可靠的定量结果。不同基质中四种加标水平（0.5、10、25、50 ng/g）的平均回收率范围为 70.9% 至 114.6%，相对标准偏差 (RSD) 低于 11.5%。使用普通设备 (HPLC-MS/MS) 的基质相关方法检测限在 0.020 至 0.140 ng/g (dw) 之间，相当于 3–130 pg/g (fw)，与高级设备（例如 UPLC-MS/MS 和 HPLC-QTOF-HRMS）的灵敏度相对应。此外，通过对中国珠江三角洲多个农场采样的实际农作物中的分析物进行测定，该方法具有实用性。
A reliable, sensitive, and efficient method was developed for routine analysis of perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS) in various edible crop matrices including cereal (grain), root vegetable (carrot), leafy vegetable (lettuce), and melon vegetable (pumpkin). The target analytes were extracted by ion-pair approach followed by solid-phase extraction clean-up and HPLC-MS/MS. The type of extraction solvent, clean-up cartridge, and the usage of Supelclean graphitized carbon were evaluated to reach an optimized pretreatment procedure. The matrix-matched standard calibrations relative to the isotope-labeled internal standard were used in the developed method to obtain more reliable quantitative results. The average recoveries at four spiked levels (0.5, 10, 25, 50 ng/g) in the diverse matrices ranged from 70.9 to 114.6% with relative standard deviations (RSD) lower than 11.5%. The matrix-dependent method detection limits using the common equipment (HPLC-MS/MS) were between 0.020 and 0.140 ng/g (dw), equivalent to the 3–130 pg/g (fw), corresponding to the sensitivity of superior equipment (e.g., UPLC-MS/MS and HPLC-QTOF-HRMS). Furthermore, the developed method was conferred with the practicality through determination of the analytes in actual crops sampled from several farms in China’s Pearl River Delta.
