我想测定金银花中的阿维菌素的残留量,净化过程我采用固相萃取技术,但是不知道使用那种类型的固相萃取柱,用没有专用的柱子,请大家指导一下,谢啦,呵呵。。。

C18净化应该也可以。
A simple multiresidue analysis method was developed for the confirmation and quantification of eprinomectin, abamectin, doramectin, and ivermectin in cattle liver. The target analytes were extracted with acetonitrile and cleaned up with C18 and [C.sub.8] solid-phase extraction cartridges before analysis by liquid chromatography combined with positive ion electrospray tandem mass spectrometry. 楼主,你能提供一下金银花里含有什么杂质吗?这个植物没有做过,不太清楚,一般都是根据含有杂质和待测组分的性质来考虑提取溶剂和净化方式
