A sensitive gas-chromatographic method for quantitative analysis of verapamil in human plasma is described. The method involves a single extraction procedure, followed by separation on a capillary column and detection with a nitrogen-phosphorus detector. The detection limit, based upon an assayed plasma volume of 0.5 ml, is 2 ng/ml. The standard curve is(More)
A rapid and simple gas chromatographic method for the simultaneous determination of malathion, parathion, fenitrothion, diazinon and carbaryl in drinking water is presented. A fused-silica SE-54 column was used for the separation of the insecticides and was split into two specific detectors; electron-capture and nitrogen-phosphorus detectors by using column(More)
