H2S Analyzer – SA4000-3 | Lazar Scientific, Inc.

H2S Analyzer – SA4000-3

The H2S Analyzer and Vapor Phase Processor (SA4015-0) are compact bench-top instruments, used to measure the total hydrogen sulfide (H2S) content of fuel oils, such as marine residual fuels, distillates, and petroleum blendstocks. The H2S Analyser can measure H2S concentrations from 0 to 250 mg/kg (ppm) in the liquid phase.

H2S is efficiently purged from the test sample by a combination of heat and agitation and is measured by a proprietary advanced gas specific detector. The instrument offers a cost-effective solution for H2S measurement – no costly or hazardous chemicals are required and there is no need for analytical preparation by an experienced chemist.

Methods: ASTM D7621, IP 570, ISO 8217

Features

Measurement range from 0-250 mg/kg H₂S (0-250 ppm H₂S) in the liquid phase
Vapour Phase Processor is proven to eliminate the effects of chemical interference
A nonchemical method, no wet chemistry involved
Small lab bench footprint, fully portable operation
Suitable for monitoring residual marine fuel blends, Crude Oil, refinery feedstock components, cargoes & products in the distribution system
Critical Measurement method for Product Safety and Release

The Vapour Phase Processor (VPP)
The Vapour Phase Processor (VPP) is used with the H2S Analyser and removes components that may affect the accuracy of the results, such as toluene, xylene, thiols (mercaptans) and alkyl sulfides.

H2S Analysis of Crude Oil
The H2S Analyser combined with the VPP offers a fast and robust means of determining H2S levels to ensure effective evaluation and treatment of crude oil. The instrument provides a cost-effective alternative to traditional methods which typically are unable to identify entrained H2S, especially at low gas levels.

H2S Global Proficiency Testing Scheme
The Seta H2S PTS scheme provides a global inter-laboratory comparison of test results and performance. Participation acts as a quality assurance program enabling users to continually monitor and validate instrument performance and results in accordance with ISO/IEC 17025.
