Abstract
A method and apparatus for detecting bonded sulfur in compounds where a discrete sample passes through a first furnace in the presence of a carrier of inert gas and is exposed to a suitable granulated metal oxide, such as copper oxide or vanadiam pentoxide, resulting in oxidation of the sulfur compound. The sample is then passed through a second furnace comingled with elemental hydrogen, there being a conversion of sulfer oxides to hydrogen sulfide. The output of the second furnace is dried. The hydrogen sulfide, along with the inert carrier gas, is introduced into a reaction chamber and is mixed with ozone. A chemiluminescent reaction occurs in the chamber, and the resulting light emission is measured photoelectrically by either a photomultiplier tube or photodiode. The output from the photomultiplier tube is connected to a summing circuit, and the summation represents the measure of sulfur in the specimen. The reaction chamber is evacuated through an outlet system so that continuous processing of samples can be achieved.
