The VPP is a new accessory for use with the H₂S Analyser to IP 570/12A Procedure A. Seta developed the VPP accessory for use with the H₂S Analyser to improve precision and accuracy of IP 570.

Primarily it addresses an issue which has been reported whereby certain chemical species in some samples will effect the sensitivity of the H₂S sensor. Additionally the VPP can be used to address a broader range of petroleum products.

The new, innovative VPP method has been developed to reliably remove the components in marine fuels and crude oils which cause unusual response curves, and give a more precise determination of the amount of H₂S present in the fuel.

Gases emitted from the H₂S analyser test vessel are passed through a cooled sorbent cartridge before they are measured by the electrochemical sensor. Hydrogen Sulfide passes through the sorbent cartridge whereas methyl mercaptans, dimethyl sulphide and other volatile chemicals are slowed or trapped by the cartridge.

New analyser software enables the instrument to differentiate if more than one peak is present and calculate the H₂S in mg/kg.

How to upgrade your H₂S Analyser

All existing Seta H₂S Analysers can be upgraded with the VPP for Procedure A compliance, by either a return to factory service or locally by a Seta authorised service partners. Factory new H₂S Analysers, when combined with the VPP, are now supplied compliant for Procedure A - simply contact Seta or your local representative.
