摘要
采用国产C_18往固相提取血中八种氨基甲酸酯,用乙酸乙酯洗脱,用气相色谱分离检定,用气相色谱/质谱进行确证。此法灵敏度为1~2μg/mL血,最低检出限为20~40ng,回收率在62~92%之间。
method for separation and detection of eight carbamate pesticides in blood is described.The blood sample was extracted with a C_18 cartridge and eluted with ethyl acetate. The eluate was separated and detected by GC and GC-MS.The sensitivities of minimum detection for the eight carbamates were in the range of 1~2μg/mL blood. The recoveries were 62~92%. The method is simple,rapid and highly sensitive.
