Abstract A detailed method write-up describing the TGS-ANSA manual procedure for measurement of NO2 in ambient air was developed. The method involves sampling for 24 hours with a restricted-orifice bubbler immersed in a triethanolamine, o-methoxyphenol, sodium metabisulfite solution. The range of the method is approximately 20 to 700 microg/cum. The method was evaluated to determine its usefulness. This involved a review of the procedure, as developed, to judge the adequacy of the development work and ruggedness testing, as described by Youden. The method was shown to be free from interferences such as: NO, SO2, O3, CO, and NH3 and possesses a constant-high collection efficiency, 93%. The time interval between the addition of the diazonium salt forming reagent and the diazonium salt coupling reagent is critical and must be carefully controlled.
