Abstract

For the GC analysis of DDT isomers and metabolites in extracts of Flores Chamomillae end Radix Valerianae the separation on a packed QF-1/OV-17 column was compared with various capillary columns of the CP-Sil type. Identification of the individual compounds could be achieved by comparing the retention behavior, chemical transformation of DDT and DDE, as well as by capillary GC-MS using single ion monitoring of substance-characteristic ion mass. In this way, residues of p,p'-DDT, o,p'-DDE and p,p'-TDE could be identified.

摘要

对于洋甘菊和缬草根提取物中滴滴涕异构体及代谢物的气相色谱分析，将填充QF - 1/OV - 17柱上的分离效果与各种CP - Sil型毛细管柱进行了比较。通过比较保留行为、滴滴涕和滴滴伊的化学转化，以及使用物质特征离子质量的单离子监测进行毛细管气相色谱 - 质谱分析，可实现对各个化合物的鉴定。通过这种方式，可鉴定出p,p'-滴滴涕、o,p'-滴滴伊和p,p'-滴滴滴的残留量。
