Abstract
The purpose of this project was to examine possible physical, physical plus chemical, and biological concepts applicable to the development of field usable test atmosphere generating devices. The primary activity for application of these devices is the round-robin survey to assess instrument/operator performance on a routine periodic basis. Ten concepts (i.e., desorption, effusion, thin film evaporators, novel permeation, radiolysis-photolysis, plasma discharge, thin films of dissolved reactants, electro-chemical films of laminated reactants, and biological generation) were examined for each of the five required pollutants (i.e., sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, and 1-butene) and a total of fifty individual discussions prepared. The program was divided into three distinct phases: (1) comprehensive literature search and preparation of technical discussions; (2) panel review of 50 discussions; and (3) comparative evaluation.
