Abstract
Conditions are described which give 95%+ conversion of sulfur to sulfur dioxide in an oxidative pyrolysis - microcoulometric determination of sulfur in hydrocarbons. There is no significant variation in combustion efficiency due to matrix effects or type of sulfur compound present. Samples containing from 0.1 to 500 ppm sulfur may be run without dilution. The mean relative standard deviation over this range is about 2.5%.
