为什么固体样品中目标分析物的浓度可以表示成微克每升?文献叫做Simultaneous determination of UV-filters and estrogens in aquatic invertebrates by modified quick, easy, cheap, effective, rugged, and safe extraction and liquid chromatography tandem mass spectrometry,我的思考是,他加标后X ng/g *绝对回收率*组织质量(g)/上机测试前复溶体积(L)换算得到微克每升这种单位,不知道对不对,欢迎大佬指教!查看更多
