Abstract
The development of a sampling and analytical method for the determination of nitrogen-dioxide (10102440) in air using poroplastic bound liquids is discussed. The background, objectives, poroplastic materials and the experimental design considerations are reviewed. The experimental techniques for the apparatus and the test atmospheres are described. The experimental protocol is presented. The experimental results for absorption, breakthrough volume, collection efficiency, stability, recovery, and accuracy are presented. The authors recommend that field status utilizing an established method as the reference should be undertaken, that extension of shelf life tests to periods of 3 to 6 months would also serve to better define the important late time plateau performance, and that this technique should now be extended to include many other gases and vapors of interest.
