Determination of Polycyclic Aromatic Hydrocarbons in Fish by GC-QqQ-MS/MS
摘要
Abstract
A new GC-QqQ-MS/MS method was developed to determine the polycyclic aromatic hydrocarbons (PAHs) in fish.In this method,the samples were pretreated by ultrasonic extraction with hexane/dichloromethane and purified with hexane/acetone on flodsil column,and then analyzed on a TR-SMS column.PAHs can be detected in the modes of electron impact ionization and selective reaction monitoring.The calibration curves had good linearity within 0.4～50 μg/kg for each pesticide (0.9999＞R＞0.9865).The limits of the detection ranged from 0.024 pg/kg to 0.06 μg/kg and the limits of quantitation ranged from 0.08 μg/kg to 0.2 ug/kg.The recoveries of PAHs varied from 68.5％ to 106.3％ with the relative standard deviations of 0.3～17.8％ at the spiked levels 5,10 and 50 μg/kg.It was satisfied with successfully determination of fish samples by this analytical approach.关键词
