EVS-EN ISO 6326-1:2010

This part of ISO 6326 gives a brief description of standardized methods that can be used for the determination of sulfur compounds in natural gas. The principle of each method is described generally, the range of concentrations for which the method is suitable is indicated, and the analytical range and precision of each method is given. It should enable the user to select judiciously the proper method for the application being considered. Sulfur analysis is performed in order to determine a) total sulfur, b)  sulfur contained in specific groups (e.g. thiol sulfur), c)  individual sulfur compounds, and d)  specific groups of sulfur compounds.
