H2S Analyser

Determination of Hydrogen Sulfide in Fuel Oil

Datasheet as PDF Questions?


The H2S Analyser with Vapour Phase Processor (VPP) is a compact bench-top instrument, used to measure the total hydrogen sulphide (H2S) content of fuel oils, such as marine residual fuels, distillates and petroleum blend stocks. The H2S Analyser can measure H2S concentrations from 0 to 250 mg/kg (ppm) in the liquid phase.

Designed with an integrated VPP, components such as toluene, xylene, thiols (mercaptans) and alkyl sulphides are removed to ensure the accuracy of results.

An analytical balance can be connected to the H2S Analyser which reads the data from the balance and automatically calculates the sample mass, saving time and eliminating the risk of data entry errors.

Other enhanced functionality features include real-time graphical display of test progress, custom result reporting and automated gas calibration.

Statistical Quality Control (SQC) software allows analysis of results in accordance with ASTM D6299. Whilst participating in the Proficiency Testing Scheme (PT Scheme) ensures continued compliance to IP 570.
