微量氧分析仪在测量时的重点是什么

  1、微量氧分析仪超级大乐透奇偶走势图带连线的配套管线应确保密封,微小的走漏都会使环境空气中的氧分散进来,从而使测量数值偏高。虽然在测量中,样气压力大于环境压力,但样气中的氧是微量级的,,氧的分压与其体积含量成正比,大气中含有约为21%的氧,与以PPM核算浓度的样气的氧分压相差一万倍左右,因此气样中微量氧的分压远低于大气中的氧分压,当出现走漏时,大气中的氧便会从走漏部位迅速分散进来。还有,取样管线应尽或许短些,接头尽或许少,要确保接头及阀门密封良好,这样微量氧分析仪的反应速度会进步许多,管线衔接完毕后,应做气密性查看。气密性查看的要求:0.25MPAm测试压力下,30分钟,压降不大于0.01MPA。
