National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Passive Monitoring for Nitrous Oxide.

PB85221323

Publication Date	1983
Personal Author	Cassinelli, M. E.; Hull, R. D.
Page Count	46
Abstract	A commercial passive nitrous-oxide (10102440) monitor was evaluated. The monitor, developed and marketed by Solid State Sensor Company, Lisle, Illinois, depended on molecular diffusion of the analyte to the collection medium. The samples were stored for up to 2 weeks before analysis. Samples were thermally desorbed and analyzed by infrared spectrophotometry. Field samples were collected in hospitals and dental offices. In the laboratory and field tests, the monitors over sampled for short exposure times and under sampled for long exposure times. None of the results were affected by humidity changes. The authors conclude that the performance of the monitor is unsatisfactory.
