PROCESS AND APPARATUS FOR THE DETECTION OF SULFUR

摘要

A process and apparatus for the detection and measurement of sulfur in both organic and inorganic sulfur-containing compounds. The process includes admixing a sample from source (10) including a sulfur-containing compound with oxygen from source (14), and then exposing the mixture to a source of combustion causing heat in the presence of a combustion supporting reducing agent (18) at combustion site (12). The resulting combustion products are extracted from the combustion site (12), directed into a low pressure chamber (20) and then contacted with ozone (22) 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.
