液液分散微萃取/GC-MS法测定婴幼儿一次性用品中5种致敏原物质
Determination of 5 Allergens in Disposable Product for Infants by Liquid-Liquid Micro-extraction Combined with GC-MS
摘要
Abstract
A new method was developed for the determination of 5 allergens (cinene,linalool,citral,benzyl acetate,cinnamaldehyde) in disposable product for infants by liquid-liquid micro-extraction combined with GC-MS.Samples were extracted with acetonitrile.The extract was dispersed with water,salted out with NaCl,and concentrated with tetrachloromethane (CCl4).The analytes were detected by GC-MS with the external standard method.The calibration curves were linear in the range of 0.01-10 mg/kg,wtih correlation coefficients more than 0.99.The detection limits were in the range of 0.01-0.1 mg/kg.The spiked recoveries were in the range of 78.7％-106％,with RSDs of 2.4％-11.3％.The result comfirmed that the method was accurate,rapid and sensitive,and was suitable for the determination of 5 allergens in disposable product for infants.关键词
