CEM - Model Series CG - Gas Converter System
From Gas Sampling System Components
The conversion of NO2 into NO depends on a catalytic reaction. Therefore, the sample gas passes the M&C gas converter type CG ... via a catalyst cartridge type C, filled up with molybdenum-coated carbon. This conversion allows an indirect nitrogen oxide measurement with all NO selctive usual commercial measuring instruments. For a ratio of NO2/NO >50% or a NO2 concentration >200ppm a filling of metal type SS is available.

Product Overview
The compact 19“-design of the M&C gas converters CG-2 and CG-2M guarantees compatible and safe handling as well as easy servicing. The 19“-rack can optional be equipped with a wall mounting bracket. The M&C gas converters CG-2H-W and CG-2MH-W are built in a wall mounting housing.
The cylindric, ready for use prepared cartridge is built into a heat-insulated tube furnace easily accessible at the front or top panel of the converter. By turning the special adapter handle the cartridge can be changed without any tools. The temperature of the cartridge can be adjusted between +50°C and 680°C at a PID temperature controller on the front panel of the converter. A status alarm contact for high and low temperature alarm is available.
Using different catalysts at specific process temperatures, the M&C gas converter CG ... is suitable for various applications. The converter is available in four versions: CG-2 and CG-2M for „cold gas“ conversion and CG-2H-W respectively CG-2MH-W with heated gas inlet, outlet and a second heating circuit for „hot gas“ conversion.
For test purposes the converter cartridge can be bypassed via 3/2-way solenoid valves out of PVDF in version CG-2M and out of stainless steel in version CG-2MH-W. Version CG-2M is equipped with two and the version CG-2MH-W with one solenoid valve. An external control is possible. The versions CG-2 and CG-2H are working without bypass valves.
Application
In many countries, clean-air regulations require a continuous measurement of nitrogen oxides NOx, as the sum of nitrogen dioxide NO2 and nitrogen monoxide NO, for combustion processes as soon as the part of NO2 exceeds 5% of the total NOx emission.
Due to the conversion to NO the use of a standard NO-analyser is possible.
