气相色谱技术的发展,尤其是高灵敏度,高选择性的电子捕获鉴定器和火焰光度鉴定器的出现,以及耐高温固定相相继出现后,对农药残留物的分析也揭开了新的一页。应用气相色谱测定农药残留量的特点是灵敏度高(ppm-ppb 级),分离效率好,速度快,可以同时测定几种或十几种农药残留物,由于上述这些特点,目前气相色谱已广泛地应用于水体、土壤、蔬菜、谷物、水果、肉类、蛋类、奶类等农药残留量的分析,并且获得了满意的结果。目前正在开展农业学大寨群众运动,各条战线都为普及大寨县而做出新的贡献。农药是农作物不可少的有效杀虫剂,并且它又直接关系到人民群众的身体
The development of gas chromatography, especially the emergence of high-sensitivity and high-selectivity electron capture and flame photometric detectors, and the appearance of high temperature-resistant stationary phases have also opened a new chapter in the analysis of pesticide residues . Application of gas chromatography for the determination of pesticide residues is characterized by high sensitivity (ppm-ppb level), separation efficiency, fast, you can simultaneously determine several or a dozen pesticide residues, due to these characteristics, the current gas chromatography has been widely It is applied to the analysis of pesticide residues in water, soil, vegetables, cereals, fruits, meat, eggs and milk, and satisfactory results have been obtained. At present, the mass movement for studying agriculture in Dazhai is under way and all fronts are making new contributions to popularizing Dazhai County. Pesticides are essential insecticides for crops, and they are directly related to people’s bodies
