| description | The invention belongs to the field of food safety detection, and discloses a method for determining pirimicarb pesticide residues in tobacco leaves by combining QuEChERS and pre-column derivatization pretreatment, specifically, after the tobacco leaves are subjected to extraction and QuEChERS purification, pre-column derivatization is carried out, derivative compounds are taken and are inspected and detected through liquid chromatography, the anti-interference ability to complex matrixes is high, the method sensitivity is high, and the method is suitable for large-scale industrial production. The accuracy and the repeatability are good, and the pretreatment is more convenient.
本发明属于食品安全检测领域，本发明公开了一种结合QuEChERS和柱前衍生前处理测定烟叶中抗蚜威农药残留的方法，具体是烟叶经过提取和QuEChERS净化后，进行柱前衍生，取衍生化合物用液相色谱检验检测，对于复杂基质的抗干扰能力强，方法灵敏度高，准确性和重复性好，前处理更便捷的检测方法。 |
