Abstract
An investigation has been made of the effects of helium, ethane, propane, nitrogen, and carbon dioxide as contaminants in methane used as the filling gas for a proportional counting tube. The concentration of contaminant was similar to that normally encountered in natural gas. It was found that the principal effect was that of change in gas multiplication factor and that compensation may be made by an appropriate change in applied bias voltage.
