建立了测定杀虫双水剂中有效成分含量的液相色谱法，并通过与现行国家标准方法比较发现，色谱法不仅简单快速、节约成本、降低污染，而且能直接测定出杀虫单有效体的含量。作者建议用杀虫单有效体的含量表示杀虫双水剂的真实质量状况。
A liquid chromatography method was established to determine the content of the active ingredients in the insecticidal water-reducing agent. Comparing with the current national standard method, it was found that chromatography was not only simple, rapid, cost-effective and pollution-reducing, Content. The author suggests that the content of insecticidal single effective body indicates the true quality of pesticide dianhydrides.
