Development of a Coulometric Method for Assessing the Concentration of Ambient Levels of CO(2)/Air in Compressed Gas Mixtures

The coulometric method presented here is a reliable method for the direct analysis of CO(2)/air cylinder gas mixtures. It is based on Faraday’s laws of electrolysis and therefore no external standardization is required. A series of CO(2)/air cylinder gas mixtures ranging in concentration from 300 to...

description The coulometric method presented here is a reliable method for the direct analysis of CO(2)/air cylinder gas mixtures. It is based on Faraday’s laws of electrolysis and therefore no external standardization is required. A series of CO(2)/air cylinder gas mixtures ranging in concentration from 300 to 375 µmol/mol (ppm) were analyzed and the results compared to those results obtained by non-dispersive infrared (NDIR) analysis with traceability to gravimetric standards. The coulometric method is rapid, sensitive, precise, and with the proper experimental controls, will yield accurate results.
