A system for measuring the amount of sulfur in a sample is provided comprising a UV fluorescence detector for determining the sulfur dioxide content of the sample and an analyzer for receiving the sulfur dioxide content of the sample from the UV fluorescence detector for evaluating the content of species under investigation and for quantifying the sulfur content in the sample. The UV fluorescence detector comprising an excimer lamp comprising a quartz envelope and a krypton-chloride excimer gas mixture therein. The quartz envelope comprising the emission aperture substantially perpendicular to the longitudinal axis of the quartz envelope for transmitting photons there through, an inner electrode comprising a conductive solid metallic rod having effective contact with the interior cylindrical surface of the quartz envelope, and an outer electrode comprising a conductive solid metallic housing having effective contact between the outer electrode and the exterior cylindrical surface of the quartz envelope, such that the quartz envelope is bounded on the interior cylindrical surface by the inner electrode and on the exterior cylindrical surface by the outer electrode. Further, the outer electrode may comprise a first member and a second member symmetrically divided along the longitudinal axis of the quartz envelope, such that when the two members are joined together to encapsulate and hold the quartz envelope there between with an interior diameter closely coinciding with the outer diameter of the quartz envelope. In another embodiment of the present invention, a UV fluorescence method for determining the sulfur dioxide content of a sample is provided.
