【摘要】 用顶空气相色谱法,测定医用透明质酸钠凝胶中乙醇残留量。采用HP-5毛细管柱;柱温:100℃;进样口温度:200℃;检测器温度:250℃;气体流速:N210ml/min,H240ml/min,Air375ml/min。结果表明:线性试验与精密度良好,回收率为96%～105%,RSD为5.6%,检出限为0.1μg/g。采用顶空气相色谱法,测定医用透明质酸钠凝胶中乙醇残留量,简便、准确。更多还原

【Abstract】 To establish a GC method for determination of the residual ethanol.The residual ethanol in medical sodium hyaluronate gel were determined by GC.The HP-5 capillary column was used,the temperature of column,injecting valve,detector were respectively 100℃,200℃,250 ℃.Result showed that the linear ranges and the precision were ideal.The recovery rate was 96%～105% with RSD of 5.1%.This GC method is simple and accurate to determine the residual ethanol in medical sodium hyaluronate gel.更多还原
