A method and system for determining a concentration level of NOx in an exhaust stream from a combustion source. The method comprises capturing sample gas from the exhaust stream using a sampling device. NO2 in the sample gas is converted to NO by passing the sample gas through a catalytic NO2 converter. 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 NO2 is performed at a temperature above the dew point temperature of the sample gas.
