IP 61 - Sulfur (High Pressure Combustion)

We perform lubricants testing by IP 61 to determine the sulfur in petroleum products such as lubricating oils with additives and some lubricating greases. The sample is placed in a high pressure decomposition device containing oxygen under pressure. The sample is then oxidized by combustion, and then the sulfur is determined by weight as barium sulfate.

We also perform sulfur analysis by ASTM D129ASTM D2622ASTM D3227ASTM D4294ASTM D5623ASTM D5453ASTM D7039IP 342ISO 3012, and UOP 163. These different test methods use different instruments or procedures or are used for certain sample types.
