  • Development of a Method for the Analysis of NO2 and NH3 by NO

    Adaptation of available instrumenfs to the analysis of NO2 and NH3 became im-portant with the introduction of the Federal Constant Volume Sampling procedure for exhaust analysis in 1970. Two instruments, the NO optical detector (NOOD) and the non-dispersive infrared analyzer (NDIR), are both fast and accurate.
