摘要
GC-MS既具有气相色谱高分离效能,又具有质谱准确鉴定化合物结构的特点,因此具备灵敏度高、定性准确、多残留可同时检测等优点,在农药残留检测中得到了广泛的应用。通常GC-MS分析方法包括样本中残留农药的提取、净化以及检测。文章论述了GC-MS进行农药残留分析样品的预处理方法,进而阐述GC-MS分析方法在检测食品及中药材中农药残留的应用。
GC - MS not only had high separation efficiency of gas chromatography but also can accurate identification of compound structure of the compound structure of mass spectrometry, which was widely used in the detection of pesticide residue, because of it had high sensitivity, exact qualitative and more residues detection. Usually GC - MS analysis methods included extraction, purification and detection of pesticide residue of the sample. GC - MS pesticide residue analysis sample pretreatment method was introduced, and it expounded the application of GC - MS in detection of pesticide residues in foodstuffs and traditional Chinese medicine.
