Abstract / scope
Specifies a method for the qualitative and quantitative analysis of sulphur compounds which may occur naturally in natural gas and remain as traces after treatment, or they have been injected deliberately to allow subsequent olfactory detection. The method is applicable to: hydrogen sulphide, methanethiol and homologues up to butanethiols, and thiacyclopentane. It is not applicable for the determination of carbonyl sulphide.
