高效液相色谱-电感耦合等离子体质谱联用同时测定鸡肉与鸡肝中的7种砷形态
Simultaneous determination of 7 arsenic species in chicken muscle and chicken liver with high performance liquid chromatography-inductively coupled plasma mass spectrometry
摘要
Abstract
A method for the simultaneous determination of 7 arsenic species was developed with high performance liquid chromatography and inductively coupled plasma mass spectrometry (HPLC-ICP-MS). The sample was extracted with artificial gastric juice. The HPLC separation was performed on an anion analytical column utilizing a gradient elution program of ammonium carbonate and water as the mobile phase. Identification and quantification were achieved by ICP-MS. Good linearities of 7 arsenic species were observed in the range from 1 μg/kg to 50 μg/kg with the correlation coefficients greater than 0. 999. The average recoveries of 7 arsenic species spiked at the three levels of 1,2 and 10 μg/kg ranged from 84.3％ to 106. 6％ with the relative standard deviations of 1.4％ - 4.2％. The quantification limits of 7 arsenic species were 1 μg/kg. The method was proved to be good reproducibility, high sensitivity and simple preprocessing. This method is suitable for the simultaneous determination of 7 arsenic species in chicken muscle and chicken liver.关键词
