Abstract

Helium is getting more and more difficult to obtain, and it does not look like that will change anytime soon. The only alternative carrier gas to helium that Agilent recommends for gas chromatography mass spectrometry is hydrogen. Converting a gas chromatograph mass spectrometer (GCMS) to use hydrogen presents additional safety concerns and may not be possible for some systems. Helium conservation, having the GCMS system use nitrogen as a carrier gas when idle, may be a viable alternative when conversion to hydrogen is not possible.

气相色谱质谱法中的氢或氦守恒:我们如何选择适合我们实验室的

氦气越来越难获得，而且这种情况短期内似乎不会改变。安捷伦推荐用于气相色谱质谱分析的唯一替代载气是氢气。将气相色谱仪(GCMS)转换为使用氢气会带来额外的安全问题，并且对于某些系统可能不可行。氦气保护，让GCMS系统在空闲时使用氮气作为载气，可能是一个可行的替代方案，当转化为氢是不可能的。
