含氮化合物的实验方法初步评价

Evalution of isolation schemes of introgenous compounds

对吡咯类含氮化合物的两种分离方法以及两步分离法中使用国产与进口试剂的实验结果进行了对比与评价。结果表明，分离方法不同，所得吡咯类含氮化合物总体馏分的丰度也不同，一步分离法普遍低于两步法；不同分离方法对吡咯类化合物相对分布的影响较小。国产与进口试剂性能不影响吡咯类含氮化合物的绝对丰度与相对分布的分析结果，两步分离法具备分析试剂国产化的条件。

The experimental results of pyrrolic nitrogen compounds isolated under conditions of two schemes (one step and two step),native and foreign reagents in the two step scheme were evaluated. It is indicated that aboudance of pyrrolic compounds in the two step scheme is higher than that in the one step one,and the relative distribution patterns of pyrrolic nitrogen compounds isolated by the two schemes are similar. Foreign reagents of silicic acid and alumina could be replaced by native ones for the very similar experimental results.
