Does the presence of Co affect liquid argon?
Thread Content
The day before yesterday, when testing the liquid argon in the storage tank, a CO content of 0.7 PPm was detected; however, it was not present in the liquid argon at the bottom of the purified argon tower. This has not happened before – has anyone encountered such a situation? Could you share your experience?
It’s carbon monoxide; I searched through books for a long time but couldn’t find any information on this topic, so it probably has little impact
There should be no impact, as the quality standards for high-purity argon do not specify any requirements regarding CO levels. The saturation temperature of CO lies between that of oxygen and nitrogen, so it is normal to find small amounts of CO in argon as well.
