Helium purity
Webthe heat exchangers of a helium-cooled reactor require knowledge of some of the thermophysical properties of the helium gas, and the same applies to the treatment of observed data in heat transfer experiments. The properties treated in this report are the density, the specific heats, the thermal conductivity, and the viscosity. WebMy Gas, the only independent Helium supplier in Southern Africa.

WebHelium is commercialized in many different purity levels from balloon gas with roughly 90 % of helium up to a purity of 6.0, which is 99.9999 % of helium. So which purity levels …
WebFor some scientific applications the required helium purity can be 99.9999% and nearly reach 100% purity for liquid application (at -269°C) – balloon gas is far short of this. Again, as the helium shortage ended in 2013 no priority was set for where helium should be used.
WebFor example, helium must meet the requirement of 99.999% purity for use as the carrier gas in an Agilent GC system. This means that the concentration of impurities should not exceed 10 ppm. Therefore, it is critical to detect ppm level impurities in helium.
