Determination of 52 Perfluorinated and Polyfluorinated Substances in Human Serum by Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry
建立了超高效液相色谱‒串联质谱(UHPLC‒MS/MS)测定人体血清中52种全氟及多氟烷基化合物(PFASs)的方法。200 μL血清样本经3 mL 0.6%甲酸‒乙酸乙酯和正己烷混合溶液(体积比3∶2)进行3次液液萃取后,采用UHPLC‒MS/MS检测分析。52种PFASs在线性范围内线性良好,相关系数(
A method for the determination of 52 perfluorinated and polyfluorinated substances(PFASs) in human serum based on ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) was developed. 200 μL human serum sample was subjected to liquid-liquid extraction three times using 3 mL of the mixed solution of 0.6% formic acid-ethyl acetate and
n
-hexane(3∶2,volume ratio),then analyzed by UHPLC-MS/MS. 52 PFASs exhibited good linearity in the range,with correlation coefficients(
r
²) ranging from 0.995 5 to 0.999 8. The limits of detection(LOD) were in the range of 0.000 9-0.015 0 μg/L,and the limit of quantitation (LOQ) were 0.002 9-0.050 0 μg/L. The spiked recoveries ranged from 75.1% to 115% with average recoveries of 78.9%-107%,the relative standard deviations(RSDs) were in the range of 1.6%-15%,and the matrix effects ranged from 85.0% to 115%. The method was used for the analysis of 180 human serum samples,and 48 PFASs were detected. Among them,the detection frequency of 12 compounds,including PFHpA,PFOA,PFNA,PFDA,PFUdA,PFDoA,PFTrDA,PFTeDA,PFHxS,PFHpS,PFOS,and 6∶2 Cl-PFAES,showed 100%. This method is simple,sensitive,accurate,and reproducible,could meet
the requirements for PFAS analysis in serum.
