超高效液相色谱-串联质谱法测定人尿液中全氟有机化合物
Determination of perfluorinated compounds in human urine by ultra high performance liquid chromatography tandem mass spectrometry
摘要
Abstract
A method for the analysis of 12 perfluorinated compounds ( PFCs ) in human urine by ultra high performance liquid chromatography-tandem mass spectrometry ( UPLC-MS/MS was developed and validated. One mL 2% formic acid in methanol was added into the urine.After ultrasonication and centrifugation , the samples were purified by a solid phase extraction column and examined by UPLC-MS/MS. The target compounds were quantified by stable isotope dilution technique. The linear range was 0.05 -50 μg/L for the 12 PFCs and the correlation coefficient ≥ 0.992. The limits of detection of 12 PFCs were in the range of 0.44 - 3.47 ng/L. The matrix recoveries of the method for the 12 PFCs in three spiked levels ( 20, 100, 500 ng/L ) ranged from 80.3% to 116.2%. The relative standard deviations ( RSDs, n = 5 ) were between 5.5% and 13.8%. The sensitive and accurate method was successfully applied to the analysis of PFCs in human urine.关键词
