A process and apparatus are disclosed for the detection and measurement of sulfur in both organic and inorganic sulfur-containing compounds. The process includes admixing a sample including a sulfur-containing compound with oxygen, and then exposing the mixture to a source of combustion causing heat in the presence of a combustion supporting reducing agent at a combustion site. The resulting gaseous combustion products are vacuum extracted from the combustion site, and then directed into a darkened low pressure chamber. The combustion products in the low pressure chamber are then contacted with ozone, with the result that the sulfur combustion products are converted to chemiluminescent sulfur dioxide. The emitted chemiluminescence is then detected, and may be measured to provide a quantitative indication of the amount of sulfur in the original sample. The preferred source of oxygen is air, the preferred form of combustion heat is a flame, and the preferred form of reducing agent is hydrogen gas.

[ What is claimed is:] [1.] A system for detection and measurement of sulfur consisting essentially of:(a) at least one first site for exposing a sulfur-containing compound to such conditions that a gaseous product is produced, said gaseous product including at least a chemical species which reacts with a gas containing at least ozone and oxygen to produce radiation in a range in which electronically excited sulfur dioxide produces radiation;(b) extraction means for removing from said first site at below-atmospheric pressure at least a portion of said gaseous product;(c) conduit means for conveying at below-atmospheric pressure said portion of said gaseous product directly from said at least one first site to a second site;(d) gas introduction means for introducing to said second site a gas containing at least ozone and oxygen to mix with said portion of said gaseous product;(e) pressure-reducing means for establishing below-atmospheric pressure at said second site, in said conduit means, and in said extraction means; and,(f) radiation detection and measuring means associated with said second site to detect and measure radiation from said second site in a range in which electronically excited sulfur dioxide produces radiation.
