高效液相色谱检测呋喃丹和甲萘威

对水样中呋喃丹和甲萘威的高效液相色谱标准检测方法进行了改进,水样使用0.45 mm滤膜过滤后直接进样200μL,以甲醇∶乙腈∶水=20∶20∶60为流动相,流量为1 mL/min,采取等梯度淋洗,荧光检测器激发波长为330 nm,吸收波长为465 nm。改进方法对呋喃丹和甲萘威的加标回收率分别为87.5%~98.6%、89.3%~105.2%,最低检出浓度分别为0.002 mg/L、0.001 mg/L,可用于水中呋喃丹和甲萘威的分析。

HPLC Detection of Carbofuran and Carbaryl

Improved the delection methods of Carbofuran and Carbaryl, directly in 200 μL water sample which had filter by 0.45 mm membrane. The mobile phase is methanohacetonitrile：water=20：20：60, 1 mL/min flow. The fluorescence detection Ex： 330 nm, Em： 465 nm. The recovery of carbofuran and carbaryl were 87.5 %-98.6 %, 89,3 %-105.2 %. The minimum detectable concentration were 0,002 mg/L, 0.001 mg/L.
