Gas analyzer 919

oxygenhydrogen sulfidemonitoring

The 919 is a fully extractive hot-wet gas analyzer, providing a complete monitoring system with sample extraction and transport, designed to maintain sample integrity. Developed to meet the requirements of the most challenging process and emissions monitoring applications in a cost-effective way, it delivers high reliability and reduced maintenance, with no moving parts. The 919’s UV measurement technology does not suffer from water (H2O) and carbon dioxide (CO2) interferences, as these species are transparent in the UV. This greatly simplifies sample handling. Fully compatible with our 900 ADA and series 9xx analyzers, the 919 is ideal for continuous emissions monitoring applications in the hydrocarbon processing and sulfuric acid industries. HIGH RESOLUTION UV TECHNOLOGY High-intensity line source lamps provide resolution better than 0.02nm. They emit at a fixed wavelength for measurement stability, and emit low total power, which removes the potential for sample photolysis. Dual-beam configuration ensures low-noise performance. UNPARALLELED LINEARITY The high resolution delivered by the UV sensing technology enables unparalleled linearity over a wide dynamic range which, in turn, leads to a simple and robust data analysis. ACCURATE CALCULATIONS The sample cell and all components in contact with the sample are heated above the dew points of all gases in the sample stream. This allows a simpler, more accurate calculation of gas concentrations, requiring no corrections for condensed and dissolved components.
