Abstract
A method and system for determining a concentration level of NOin an exhaust stream from a combustion source. The method comprises capturing sample gas from the exhaust stream using a sampling device. NOin the sample gas is converted to NO by passing the sample gas through a catalytic NOconverter. The method also comprises removing water from the sample gas by passing the sample gas through a dryer and determining a sample gas NO concentration level. The step of converting NOis performed at a temperature above the dew point temperature of the sample gas.
