【求助】有做过土壤中的灭多威的吗？

楼主，您可以参考一下这篇文献：
[url=https://insevent.instrument.com.cn/t/Mp]气相色谱法测定烟草中灭多威残留量[/url]

还真没有看到用GC/FPD检测灭多威的,标准没有出峰,应该是检测器问题,再高浓度试一试,我们是用NPD\LC\GC/MS检测的.

我们的灭多威是用LCMS检的.好像GCMS上没有峰.

很可能是检测器的问题,灭多威一般是用液相检测.

灭多威用GC测定的文献不是很多：
Direct gas chromatographic determination of methomyl (lannate®) with microcoulometric nitrogen detection
I. H. Williams

Abstract：
A microcoulometric method is described for the direct determination of nanogram amounts of methomyl (S-methyl-N-[(methylcarbamoyl)-oxy]thioacetimidate). An all-glass gas chromatographic system coupled to a microcoulometer with a nitrogen-specific cell was used. The column was packed with a mixture of 6% OV210 and 4% OV101 on Gas Chrom Q, as was the glass transfer tube which connected the chromatographic column to the pyrolysis furnace. Some loss occurred but response was linear from 125 to 20 ng and sensitivity was such that 20 ng of methomyl could be readily measured.

楼主，适当升高柱温再试试。浓度高一些响应会好的多。
