Sulfur analyzer 6200T / 6200E

for the food industryfoodtrace

The Model 6200T Total Sulfur Analyzer utilizes proven UV fluorescent technology to continuously detect sulfur found in inert gas streams. An internal, quartz catalytic converter is employed to convert the sulfur, when mixed with scrubbed ambient air, into SO2 via higher temperature oxidation. An internal vacuum pump is employed to draw both the sample and the ambient air into the converter. The converted sample gas is fed to the fluorescence chamber where it is then exposed to ultraviolet radiation.​ Measurement Process The measurement process in the reaction cell is described by the following equation: SO + hu1 -> SO2* SO* -> SO2 + hu2​​ Where hu1 is the incident UV energy at 214nm and hu2 is the resultant fluorescence, which is directly proportional to the SO2 concentration in the reaction cell. The fluorescence emission is in turn sensed by the photomultiplier tube (PMT) and amplified to provide an analog output. The result is a continuous measurement of total sulfur (i.e. H2S, CS2, COS, mercaptans​, etc.) as SO2 from 0-50 ppm to 0-20 ppm.
