H2S Gas Analyzer
H2S Gas Analyzer Description
The H2S Analyzer with Vapour Phase Processor (VPP) is a compact bench-top instrument, used to measure the total hydrogen sulphide content of fuel oils, such as marine residual fuels, distillates and petroleum blend stocks. The Hydrogen Sulfide Analyzer (H2S Gas Analyser) can measure concentrations from 0 to 250 ppm in the liquid phase.
Designed with an integrated and at -20 Deg C 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 the ASTM D6299 H2S analyzer standard.
A limit of 2 parts-per-million (2 ppm) in the liquid phase was set by the industry in 2012 under ISO 8217, which made IP 570 Procedure A the referee test for this ASTM D6299 H2S analyzer.
As a trusted H2S analyzer supplier, we proudly provide top-tier sales, calibration, and support services to the energy and maritime sectors across the UAE, Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain.
