摘要

研究了单旋TiO萃取- 9-氟酰甲氧羰基氯(FMOC-Cl)衍生-同位素稀释质谱法(IDMS)测定人尿中草甘膦(Gly)含量的方法并进行了优化。优化条件下,FMOC-Gly的定量限为0.3µg/kg,与前人研究结果相当或更低。在优化的分析条件下,对人尿样品进行尖峰检测,FMOC-Gly的准确率为:尖峰水平为0.5µg/kg时为101.6 ~ 104.9%,尖峰水平为30µg/kg时为99.2 ~ 101.0%。日内重复性和日内重复性均<6.5%。“有”衍生化和“没有”衍生化方法之间验证的峰值测试结果在1µg/kg时具有可比性。本研究结果表明,单旋体TiO萃取和IDMS - FMOC-Cl衍生化是一种准确分析人尿中甘氨酸的方法。

A simple reliable quantification of glyphosate in human urine using MonoSpin TiO extraction and isotope dilution mass spectrometry
A method of quantifying glyphosate (Gly) in human urine by means of MonoSpin TiO extraction and 9-fluorenylmethoxycarbonyl chloride (FMOC-Cl) derivatization with isotope dilution mass spectrometry (IDMS) was investigated and optimized. The method’s quantification limit under optimized conditions was 0.3 µg/kg for FMOC-Gly, which was comparable to or lower than those described in previous studies. When a spike test using human urine samples was carried out with optimized analytical conditions, the trueness for FMOC-Gly was as follows: 101.6–104.9% for a spike level of 0.5 µg/kg and 99.2–101.0% for a spike level of 30 µg/kg. The intra-day repeatability and inter-day reproducibility were <6.5%. The spike test results for validation between the “with” and “without” derivatization methods were comparable at 1 µg/kg. Our results indicate that using MonoSpin TiO extraction and FMOC-Cl derivatization with IDMS is an accurate method for analyzing Gly in human urine.
