25%苯丁锡·螺螨酯悬浮剂是由20%苯丁锡和5%螺螨酯复配而成。它是一种高效广谱杀螨制剂,可用于防治柑橘红蜘蛛,深受广大农民的欢迎。但是关于二者复配制剂的同条件分析方法,目前尚未见报道。本文建立了在同一液相色谱条件下同柱分离测定苯丁锡和螺螨酯的方法。实验结果表明该方法操作简便,分离效果好,准确度和精密度高。1实验部分1.1仪器与试剂日本岛津公司LC-10A型高效液相色谱仪、
25% Butyltin · Spirodiclofen Suspension is composed of 20% butyltin and 5% spirodiclofen mixture made. It is a highly effective broad-spectrum acaroid preparation that can be used to prevent and cure citrus red spider and is welcomed by many peasants. However, there is no report on the same condition analysis method of the two formulations. In this paper, a method for the simultaneous determination of dibutyltin and spirodiclofen in the same liquid chromatographic conditions was established. Experimental results show that the method is easy to operate, the separation effect is good, the accuracy and precision are high. 1 Experimental 1.1 Instruments and reagents Japan’s Shimadzu LC-10A-type high performance liquid chromatography,
