气相色谱法测定霜脲氰原药含量

Determination of Cymoxanil in Technical Material by Gas Chromatography

本文介绍了用气相色谱法测定霜脲氰原药含量的定量分析方法。色谱柱采用５％ＯＶ－１０１／ＣｈｒｏｍｏｓｏｒｂＷＨＰ（８０～１００目）内径２毫米×０５米不锈钢柱，氢焰离子化检测器。该法添加回收率在９７６～１０３８％之间，相对标准偏差０２１。

A quantitative method to analyze cymoxanil content in technical product was described in this paper.By using GC with FI detector on stainless steel column(0.5m×0.2mm)packed with 5% OV-101/Chromosorb and n-heptadecane as internal standard,the recovery was 97.6～103.8% and relative standard deviation was 0.23%.
