Description: A commercially available laboratory model helium purifier which operates on the principle of preferential diffusion of helium through quartz tubes was evaluated to determine the purity of the effluent helium. Analysis of the effluent helium from the purifier showed that its utility was limited because of an anomalous evolution evolution of hydrogen and the significant diffusion of neon through the quartz tubes.
