水中溶解氢气的分析方法大致可以分为经典方法和仪器分析方法。经典方法须将水中的氢气解吸出来,然后用燃烧法测定,此方法需用水样品量较大。而用气相色谱法分析溶解于水中的永久性气体,又可以采用多种方式。但是,如何把水中所溶解的氢气从液相转入气相,然后用色谱仪检测,仍然是值得加以改进的。本文采用直接进样法,使操作简便。 Hydrogen dissolved in water can be roughly divided into classical methods and instrumental analysis methods. The classical method to desorb the hydrogen from the water, and then measured by the combustion method, this method requires a larger sample of water. The use of gas chromatography analysis of dissolved in water, a permanent gas, you can also use a variety of ways. However, how to transfer the dissolved hydrogen in the water from the liquid phase to the gas phase and then detect it with a chromatograph still deserves to be improved. In this paper, direct injection method, so easy to operate.
