TSA-100 sulfur analyzer

Insusceptible to component cross-interference, the solid-state TSA-100 sulfur analyzer provides accurate total sulfur measurements, even when H2S, SO2 and mercaptans are present in the sample. It works by having a xenon light source send light through fiber optic cables into a flow cell, where the sample’s unique characteristics dictate its interaction with the light. The light enters a holographic grating, which separates white light into its components, such that a diode array detector can measure the intensity of radiation at each wavelength. As measurements report on the absorption of light by the sample comp- onents, the concentrations of the components are revealed. Because fiber optic cables are used, the analyzer can be installed far from explosive or poisonous gases. The diode array produces full high-resolution spectrum analysis, enabling easy switches between extreme wavelength ranges to provide instantaneous and continuous measurements at 0–10 ppm and 0–100%. The device can measure total sulfur content in two ways. One is the standard method, in which the hydrocarbon sample is placed in a hot combustion tube with an oxygen-rich environment, where the sulfur oxidizes to SO2. The analyzer uses the absorption of the SO2 to determine the concentration of the single component and total sulfur. The other is the direct method, in which the analyzer mathematically derives the concentration of each sulfur compound from the original process stream’s high-resolution absorbance spectra.
