气相色谱仪测定蔬菜有机磷类农药残留时标样校正曲线对测定结果的影响

Effect of Calibration Curve on Determination of Organic Phosphorus Pesticide Residues in Vegetables by Gas Chromatograph

通过不同标样浓度下校正曲线对蔬菜有机磷进行加标回收试验,研究有机磷类农药单点、多点标样浓度下标准曲线的浓度值对农药残留测定结果的影响,试图寻找准确性良好的有机磷类农药残留检测方法,为农产品质量安全提供有效、准确依据。

Through the calibration curves under different sample concentration of vegetables organic phosphorus standard addition recovery test, the research of organic phosphorus pesticide single point, multi-point sample concentration under the standard curve of density on the result of determination of pesticide residues, trying to find a good accuracy of organic phosphorus pesticide residues detection method, provides the effective and accurate basis for the quality and safety of agricultural products.
