Carbaryl (1-naphthyl methylcarbamate), Mesurol® (4-methylthio-3,5-xylyl methylcarbamate), promecarb (m-cym-5-yl methylcarbamate) , Zectran® (4-dimethylamino-3,5-xylyl methylcarbamate), and 4-dimethylamino-3,5- xylenol were successfully chromatographed on Chromosorb W support, surface-modified with Carbowax 20M. The intact compounds were detected by means of the nitrogen or sulfur response of an alkali flame detector. Calibration curves were linear over the range 4 to 2000 ng. Average pesticide recoveries of 90—100% were obtained from fortified vegetable samples.
