Apparatus for Hydrogen Sulfide Tester – AZA 1314
The Apparatus for Hydrogen Sulfide Tester (Model: AZA-1314) from AZA Lab conforms to the ASTM D7621 Standard Test Method for the determination of hydrogen sulfide in fuel oils by rapid liquid phase extraction.
In this method, a weighed test sample is placed into a heated vessel containing a diluent base oil, where air is bubbled through to extract hydrogen sulfide gas. The extracted gas is then directed, via a vapor phase processor (Procedure A), to an H₂S-specific electrochemical detector, which measures its concentration in air and calculates the amount in the liquid phase in mg/kg. For Procedure B, the use of a filter cartridge is not required.
