氢气纯度对柱效的影响及对柱使用寿命的影响

简介：氢气纯度对柱效的影响及对柱使用寿命的影响 Hydrogen has been widely adopted as a carrier gas to replace nitrogen and helium in GC applications for a variety of reasons. Superior advantages include faster analysis, lower cost and the reliability of supply that hydrogen (generated on-site) offers. The purity of carrier gas is crucial for higher performance, lower maintenance and the longevity of analytical instruments. High purity carrier gas lowers baseline noise and provides better sensitivity and longer column and gas trap life. The required purity for hydrogen carrier gas is 99.9999% (research grade) for trace work under 1 ppm, or at least 99.9995% for most normal analyses. Recent analyses from two third-party testing laboratories aid in understanding the importance of using research grade hydrogen gas generators to supply carrier gas to analytical instruments. This paper focuses on evaluating different hydrogen sources and addressing the benefits of using research

为什么使用在线氢气发生器会得到更好的测量结果

简介：为什么使用在线氢气发生器会得到更好的测量结果 Why Switching to On-Site Hydrogen Leads to Better Results Laboratory practitioners need a carrier gas they can count on. But helium – traditionally used as a gas chromatography (GC) carrier gas – supplies are dwindling, forcing laboratories to pay more and risk a missed delivery of this ever more scarce gas. Laboratories are increasingly looking for a more reliable and less expensive solution than helium gas. The only carrier gas that can offer higher reliability and lower cost – plus faster results – is hydrogen, made on-site. A hydrogen generator using a Proton Exchange Membrane (PEM) electrolyzer safely and reliably produces an endless supply of ultra-pure hydrogen at a fraction of the cost of delivered helium.
