Abstract |
A Monsanto Model 3409 Chemiluminescent Ambient Air Monitor was converted to a two-channel configuration for simultaneously monitoring NOx and SO2 in stack gases. Channel separation was obtained by means of narrow-band optical filters. The analog sample-hold part of the automatic zero circuit was replaced by a digital memory circuit. A permeation dryer was included to remove water from the sample. The atomic oxygen source was changed to an ozone generator-thermal decomposition configuration. A microwave oxygen generator was also tested. (Modified author abstract) |
