ASTM D7551:

ASTM D7551 is the Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases and Natural Gas by Ultraviolet Fluorescence

This test method covers the determination of total volatile Sulfur in gaseous hydrocarbons, Liquefied Petroleum Gases (LPG) and Liquefied Natural Gas (LNG). ASTM D7551 is applicable to analysis of natural gaseous fuels, process intermediates, final product hydrocarbons and generic gaseous fuels containing sulfur in the range of 1 to 200 mg/kg.

The TSHR NEXIS TS, NEXIS VP TS and TS 6000/7000 Total Sulfur analyzers are fully compliant with the ASTM D7551 method. Full automated analysis can be achieved with the NEXIS GM and GM 7000 Gas & LPG sample introduction module connected to one of the above analyzer models.
