气相色谱法测定除草剂吡嘧黄隆

Gas Chromatographic (GC) Determination of Pyrazosulfuron

气相色谱法测定除草剂吡嘧黄隆郭兴杰（沈阳药科大学分析教研室沈阳１１００１５）１前言吡嘧黄隆为国内新引进的磺酰脲类除草剂，具有优良的除草活性，尤其应用于稻田。关于吡嘧黄隆的含量分析方法，国内已见报道的仅有高效液相色谱法〔１〕本文研究了用气相色谱法测定吡...

A gas chromatography method for the quantitative analysis of pyrazosulfuron is described. Analytical conditions were as follows:column:OV-225 (5% )on Chromosorb W AW DMCS(60-80 mesh),2m column with 3mm i.d.at 172℃;FID at 260℃;N2 as carrier gas with flow rate of 30mL/min.
