摘　　要：色谱法是一种重要的分离分析方法,它是利用不同物质在两相中具有不同的分配系数,当两相做相对运动时,这些物质在两相中进行多次反复分配而实现分离。气相色谱法是流动相为气体的一类色谱分析法。为此,对气相色谱仪在农业生产中的应用前景进行了分析。在农业生产中常用气相色谱仪检测蔬菜中有机磷、有机氯、菊酯类及氨基甲酸酯类等农残,且在农业等许多领域都有着广阔的应用前景。Chromatography is an important method of separation and analysis. It depends on different substances in the two phases having different coefficients. When the two - phase do the relative movement, these substances in the two phase repeat several times to achieve separation of distribution. Gas chromatography is an method of chromatograph for mobile phase for gas. Gas chromatograph is commonly used in detection organic phosphorus, organic chlorine, pyrethroid and earbamate pesticide residues in vegetables in agricultural production. Gas chromatograph is especially suitable for sensitive sectors of quality supervision, inspection and control. This shows that gas chromatograph have a wide application prospect in agriculture and many other fields.
