高效液相色谱法分析硫双灭多威

研究了用高效液相色谱分析杀虫剂硫双灭多威的方法。在反相ＯＤＳ柱上，用甲醇－水作流动相，紫外检测器检测，以邻苯二甲酸二甲酯作内标定量。方法快速、准确，重现性好，线性范围宽，变异系数为０．１８％，回收率为９９．８９％，色谱分析周期仅为８ｍｉｎ。

Determination of thiodicarb by reversed-phase high performance liquid chromatography]

In this paper, a method for determination of thiodicarb by reversed-phase high performance liquid chromatography (RP-HPLC) is presented. Analysis was performed on a 250 mm x 4.6 mm i.d. octadecylsilica (ODS or C18) bonded phase column in 8 minutes. Methanol/water mobile phase was used. Ultraviolet detector was used for detection at 232 nm wavelength. The internal standard method (using dimethyl phthalate as the internal standard) was employed. The linearity of the method was verified. The relative standard deviation (RSD) of determination for 75% thiodicarb wetted-powder was 0.18%. The average recovery was 99.89%. The method has been used for analysis of pesticide products and control of production.
