Continuous Pre- and Post- Catalyst Hydrocarbon and Nitrogen Compounds-Monitoring of Various DeNOx Reactions by Twin Chemical Ionization Mass Spectrometry 2002-01-1679

Today's concepts of dynamic emission control in lean operating engines demand rapid monitoring of all relevant molecular components and their concentrations in pre- and post-catalyst exhaust gas.
Storage capacities and breakthrough characteristics of catalysts, reaction rates, response times and interference levels in NO sensors are no longer studied in stationary gas distributions; they must be evaluated under transient conditions [1].
A twin chemical ionization mass spectrometer (CIMS) system, enables simultaneous and synchronous monitoring of relevant gaseous components with dynamic capabilities from 0.1 ppm to 5000 ppm and a high time resolution.
