用加速溶剂萃取法（ ASE）萃取土壤中的有机磷农药，用气相色谱-负化学离子化质谱法（ GC-NCI-MS）进行测定，并与气相色谱-电子轰击电离质谱法（ GC-EI-MS）进行了对比。结果表明，EI法和NCI法均能满足目前的有机磷农药的分析需要。 GC-EI-MS的适用范围比较广，操作比较简单；GC-NCI-MS在选择性和灵敏度等方面均具有较强优势。

An effective method for trace analysis of organophosphorus pesticides in soil was developed using accelerated solvent extraction ( ASE) followed by gas chromatography-electron ionization-mass spectrometry ( GC-EI-MS) and gas chromatography-negative chemical ionization- mass spectrometry ( GC-NCI-MS ) . The results show that both GC-EI-MS and GC-NCI-MS are sufficient for the daily analysis. GC-EI-MS method has an extensive application scope and is easy to operate. Also the GC-NCI-MS method has advantages in selectivity and sensitivity.
