In order to apply gas discharge purification of helium in chromotographic analysis, the authors have carried out the separation process in the present work at a pressure above the atmospheric pressure. They then carry out the purification in an arc discharge, because it is difficult to achieve a stationary glow discharge at atmospheric pressure. Cylinder discharge chambers were used in the experiments, made of stainless steel with Teflon flanges. A decrease in the nitrogen content by a factor of 7-10 has been obtained in the experiments. The proposed method can be used for the purification of helium from cylinders in different variants of chromatographic analysis.
