A sulphur and carbon analyser is an instrument used to determine the sulphur and carbon content in marine and aviation fuels and other substances under laboratory conditions. The main component of the analyser is an induction furnace. In this furnace, the sample is melted in an atmosphere of pure oxygen, causing the sulphur to be converted into sulphur dioxide (SO₂) and the carbon into a mixture of carbon monoxide (CO) and carbon dioxide (CO₂).
