反应效果好的还是得过柱子算分离产率。【要发差一点的杂志大概可以随意。】
A combination of total ion chromatograms (TICs) and extracted ion chromatograms (EICs) was used. The optimisation and validation of the method have been carried out according to current international guidelines. Adequate sensitivity was demonstrated in the selected concentration ranges for most of the...
