Testing and analysis of sulfur compounds in petroleum and refined products.

Intertek petroleum laboratories identify and quantify sulfur compounds in crude oil, petroleum feedstocks, and refined petroleum products. Sulfur compounds occur in various types and quantities in hydrocarbon feedstocks and refined products, including gasoline, diesel and many other fuels and materials. 

Using ASTM, ISO, and other industry accepted tests, Intertek labs detect, quantify, and speciate the diverse sulfur compounds found in petroleum gases and liquids. Sulfur compound analysis can reach to trace and ultra-trace levels. Laboratory experts help clients trouble-shoot sulfur related problems and improve quality and process control.

Analysis of sulfur molecular species (speciation) provides useful data for mitigating sulfur compound problems in petroleum refined products, providing greater insight than measuring total sulfur content alone.

Sulfur compound testing:

  • Sulfur speciation, ASTM D5504, D5623, other tests
  • Sulfur content, ASTM D2784, D3246, D4294, D4045, D4468, D5453, D6667, D7039, ISO 20846, other tests
  • Sulfate content, ASTM 7318, D7319, D7328, other tests
