The Stanhope-Seta H2S crude oil analyzer, combined with a vapour phase processor (VPP), offers a fast and robust means of determining H2S levels to ensure efficient treatment of crudes. The instrument provides a cost-effective alternative to traditional methods which cannot offer a true indication of H2S especially at low gas levels. Measurement ranges from 0-250 mg/kg H2S (0-250 ppm H2S) in the liquid phase. Meets ASTM D7621, IP 570. This is a non-chemical method, so no wet chemistry is involved. Suitable for monitoring residual marine fuel blends, crude oil, refinery feedstock components, as well as cargos and products in the distribution system. Hoskin Scientific
