All sources of carbon dioxide have source specific impurities that can be present in variable concentrations, the levels are reduced by gas purification plants operated by industrial gas producers, however small traces can still be present. It is also possible that contamination of purified product can occur through handling and distribution or cross-contamination of the product.
