毛细管气相色谱法测定三苯基膦的含量
前言:采用10m×0.25mmidOV-101石英毛细管柱,氢火焰检测器(FID),蒽酮作内标物,建立了毛细管气相色谱法分析三苯基膦的方法。该法快速、准确,其回收率为99.2%—100.3%。
In this paper,a method was established for the determination of the content of triphenyl phosphine by a 10m×0 25mm i.d.OV 101 fused silica capillary column and FID detector The column temperature was programmed from 130℃ to 250℃ at 20℃/min The internal standard was anthrone It was rapid and accurate,and could be easily used for industrial process The recovery of triphenyl phosphine ranged from 99 2% 100 3%
