摘要
结合半导体制冷技术,建立了一种气相色谱在线除水方法,该法具有节约载气、减少干燥剂用量、样品消耗量小等优点。采用该装置,气相色谱法测定溶解态N2O,可有效消除水汽的干扰,仪器连续运行15 h基线漂移的变异系数优于0.6%。
The traditional moisture trap method and semi-conductive refrigerate technique were combined to remove the moisture. The new technique could reduce the amount of reagent, the sample volume, as well as the consumption of carrier gases. The interference of water vapor was eliminated and N2O in solution was determined by gas chomatography, the variance coefficient of the instrument is better than 0.6% after 15 h operation.
