H2S Analyser

Part Number SA4000-3

IP 570 ‘Determination of Hydrogen Sulfide in Fuel Oil – Rapid Liquid Phase Extraction Method’

The H2S Analyser was originally developed in cooperation with Lloyd’s Register’s ‘Fuel Oil and Bunker Analysis Service’ (FOBAS) along with support of other major international oil companies to offer rapid measurement of H2S in liquid petroleum products.

The H2S Analyser is an excellent tool for supporting Quality Control and safety ensuring product is within approved specification. Rapid repeat sample measurement means it can also be used to assist product remediation treatment of feedstocks and off specification product.

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.

The Vapour Phase Processor (VPP)

IP 570, procedure A includes the VPP accessory which provides a more robust specification tool for monitoring H2S. This is achieved by removing any interfering chemicals such as toluene, xylene or Mercaptans which can damage the sensor and ‘interfere’ with readings. Additionally the VPP can be used to address a broader range of petroleum products.

H2S Analysis of Crude Oil ASTM D7621, appendix X1

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 global inter-laboratory comparison of test results and performance. Participation acts as a quality assurance programme enabling users to continually monitor and validate instrument performance and results in accordance with ISO/IEC 17025.
