一、前言: 氧中微量氢浓度分析,可以由很多方法来实现: 1.以氢的电化学性质为出发点,制作两个半电池,通过电位差的测量来实现氢含量测定。2.采用间接的办法,将氢和氧转化成水,然后再对微量水份进行测量。而微量水份的分析有比较现成的办法。我们曾对这一技术路线进行过探索,结果发现: (1)气样中残余水份难以除尽。(2)没有找到一种合适的触媒,既能使 First, the preamble: trace oxygen in the oxygen concentration analysis, can be achieved by many ways: 1. The electrochemical properties of hydrogen as the starting point, making two half-cell, through the potential difference measurement to determine the hydrogen content. 2. Using indirect methods, convert hydrogen and oxygen to water, then measure trace amounts of water. The trace moisture analysis has more ready-made approach. We have explored this technical route and found that: (1) residual moisture in gas samples is hard to divide. (2) did not find a suitable catalyst, both can make
