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 on 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.
使用霍尔电解电导率检测器研究了32种氨基甲酸酯类农药的气相色谱行为。成功测定了24种氨基甲酸酯类在六种不同色谱柱上的相对保留指数。所研究的色谱柱包括超键合柱、超键合柱上3%的OV-101、超键合柱上1%的OV-17、超键合柱上1%的OV-210、超键合柱上1%的聚乙二醇20M以及超键合柱上0.5%的OV-210 + 0.65%的OV-17。采用化学电离气相色谱-质谱联用技术验证氨基甲酸酯类农药在色谱分离过程中保持完整。报告了化学电离质谱图。展示了测定土壤中氨基甲酸酯类残留量的分析方法。
