  • 摘要:In order to establish efficiently the operating conditions of gas chromatography (GC-FPD) for organophosphorus pesticides, relative retention times (RRT) to parathion and appraisal of separation for 34 pesticides were investigated on serveral liquid phases. Seven liquid phases that were selected on the basis of McReynolds constant were OV-1 as low polarity, DC-200+EPON 1009, OV-17, QF-1, XE-60 as moderate polarity and PEG-20M, DEGS as high polarity. It was found that moderately polar liquid phases such as DC-200+EPON1009, OV-17, QF-1 and XE-60 were most suitable for the analysis of these pesticides. Detection limits were in the range of 0.05 to 10 ng for the most part of them. Polar pesticides were fine for polar liquid phases such as XE-60, DEGS. Combined application of these liquid phases in which RRTs turn over each other should be effected for complete certification on GC analysis. Next, RRTs of 34 pesticides were plotted on the diagram with McReynolds constant to vertical line and RRT to horizontal line. By practical use of this diagram, it would be easy to grasp the character of an organophosphorus pesticide, to infer the behavior of one among liquid phases. Besides, suitable operating conditions of GC for the determination of a pesticide will be easily chosen due to this RRT diagram.
