摘要：

The gas chromatographic behavior of 32 carbamate pesticides was investigated using the Hall electrolytic conductivity detector. Relative retention indices were successfully determined for 24 carbamates on six different columns. Columns investigated included Ultra-Bond, 3% OV-101 on Ultra-Bond, 1% OV-17 on Ultra-Bond, 1 % OV-210 an Ultra Bond, 1 % Carbowax 20M on Ultra-Bond and 0.5 % OV-210 + 0.65% OV-17 on Ultra-Bond. Chemical-ionization gas chromatography-mass spectrometry was used to verify that the carbamates were chromatographed intact. Chemical-ionization mass spectra are reported. Analytical procedures are demonstrated for the determination of carbamate residue in soil. © 1979.
