Determination of Residual Methanol in YAN-SHENG HEALTH LIQUID by Headspace Gas Chromatography

    摘要
  • 摘要: 本文用顶空气相色谱法,以GDX-101为固定相,测定了延生护宝液中甲醇残留量,方法的回收率在85.9%-101.6%之间,变异系数0.3%,最小检出量1.0mg/L.

     

    Abstract: Headspace gas chromatography for determination of residual methanol in YAN SHENG HEALTH LIQUID,A GDX-101 column and FID were used. The recoveries were from 85.9% to 101.6% the R. S. D value were 0.39%.
