Abstract
A total sulfur analyzer system is set forth. The system operates with gas, liquid or solid samples including free sulfur, and sulfur and nitrogen compounds. The sample is first combusted to provide products of combustion including SO.sub.2 and NO. The SO.sub.2 quantity is measured by exposure to a particular frequency of ultraviolet light to obtain fluorescence, the fluorescent photons being measured by a photomultiplier tube (PMT). The system preferably includes suitable elecronics connected to the PMT for providing data of measurements of sulfur.
