Description
The 919 is the hot-wet UV photometric gas analyzer for challenging process and emissions monitoring. The 919 Hot/Wet UV Single Gas Analyzer was designed to meet the requirements of the most challenging process and emissions monitoring applications in a cost-effective fashion. It is a complete system with a sample extraction and transport designed to maintain sample integrity.
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. UV measurements do not suffer from water (H2O) and carbon dioxide (CO2) interference as these species are transparent in the UV. This greatly simplifies sample handling.
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. An optional oxygen (O2) sensor can be included.
KEY BENEFITS
