Natural gas. Determination of water by the Karl Fischer method - Coulometric procedure Ingestion-build-276583 Why should you use DD1 Scope This part of ISO 10101 specifies a coulometric procedure for the direct determination of water content by the Karl Fischer method. The method applies to natural gas and other gases which do not react with Karl Fischer reagents. It applies to water concentrations between 5 mg m3 and 5 000 mg m3. Volumes are expressed a temperature of 273,15 K (0 C) and a pressure of 101,325 kPa (1 atm).
