EC9842T Trace Ammonia Analyzer - Ecotech - #1

Text version of the page

EC9842T Trace Ammonia Analyzer The EC9842T Chemiluminescence NH3 trace analyser combines a high performance ammonia converter and proven chemiluminescence detection to measure ammonia (NH3 ), oxides of nitrogen (NOx) and total nitrogen compounds (Nx). Nx is the sum of NO+NO2+ NH3 i.e. total oxides of nitrogen including ammonia. The EC9842T features a higher sample flow rate and heated valve manifold to improve NH3 response time. The higher operating vacuum in the reaction cell improves the signal to noise ratio and facilitates greater sensitivity for the detection of low levels of Ammonia (NH3). The Ecotech EC9842T utilizes an external platinum (Pt) converter operating at 680°C to convert Ammonia (NH3) to NO. The resulting NO is detected by the Chemiluminescence reaction of NO with ozone inside the reaction cell. • The analyzer is easy to use in the field with a specifically designed external Ammonia converter with low absorption wetted parts • EC9842T is based on the EC9841T which is an U.S. EPA approved technology (Automated Reference Method RFNA-1292-090) • Specifically designed for background monitoring with a range of 0-2000 ppb and a LDL of 400 ppt • Concentrations are automatically corrected for gas temperature and pressure changes and can be displayed in units of ppt, ppb, ppm, ug/m3 or mg/m3 • Kalman digital filter continuously provides the best compromise between response time and noise reduction • Internal data logging using Flash ROM of up to 135 days of 5 minute data averages • Increased ozone to sample ratio reduces CO2 and H2O quenching effects • Operates at a lower reaction cell pressure (i.e. fewer molecules in the reaction cell means less interference due to collisions between NO and H2O/CO2 molecules) • Ozone air source is scrubbed with Purafil® to reduce contaminants in the measurement cell • Full external remote control capability, up to 166 analysers parameters may be access via the USB port • User up-gradable firmware via USB or RS232 port Features
