H₂S Analyser with Vapour Phase Processor – SA4000-4

Methods ASTM D7621 | IP 570 | ISO/PAS 23263 | ISO 8217 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. 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 H2S. IP 570 includes the use of verification fluids as a recommended practice. Participation within a Proficiency Test Scheme (PT Scheme) is stated as the preferred means to achieve this.
