探讨了高效液相色谱-大气压化学电离质谱联用技术在农药分析中的应用。本研究选用了21种有机磷农药和8种N-甲基氨基甲酸酯类农药。我们同时监测了21种有机磷农药的正负离子。而8种N-甲基氨基甲酸酯类农药只能用正离子检测模式检测。尽管从该方法获得的质谱显示出比用电子碰撞方法获得的质谱更简单的模式，但这些质谱足够清晰，可以识别色谱图上的未知峰。由于该方法具有高度的特异性，可以用非常简单的前处理过程进行快速分析。我们认为，这种测量方法可以是一个非常强大的手段，农药分析。
An application of high-performance liquid chromatography-atmospheric pressure chemical ionization mass spectrometry for pesticides analysis is discussed. 21 types of organophosphorus and 8 types of N-methylcarbamate pesticides were selected for in this study. We monitored both positive and negative ions to identify 21 organophosphorus pesticides. However, 8 N-methylcarbamate pesticides were detectable only with the positive ion measurement mode. Although the mass spectra obtained from this method showed a simpler pattern than those obtained with an electron impact method, those mass spectra were distinct enough to identify unknown peaks on the chromatogram. Because of the high specificity of this method, quick analysis could be performed with an extremely simple pre-treatment process. We suggest that this measurement method can be an extremely powerful means of pesticide analysis.
