Device to eliminate erroneous output in cyclic chemiluminescent nitrogen dioxide monitoring

The NO 2 signal of a current cyclic chemiluminescent monitor is seriously affected by changes of the NO concentration within one cycle. A device is described to eliminate this. Instead of successive sampling for NO and NO x immediately followed by analysis, sampling is done in the NO part of the cyc...

Description
Summary:The NO 2 signal of a current cyclic chemiluminescent monitor is seriously affected by changes of the NO concentration within one cycle. A device is described to eliminate this. Instead of successive sampling for NO and NO x immediately followed by analysis, sampling is done in the NO part of the cycle for both measurements. Transportation of the NO x sample is delayed until the NO measurement has been finished. The NO 2 signal of a cyclic chemiluminescent instrument, modified in this way, showed a maximum deviation of 3% with respect to any instantaneous changes in NO concentration.
