Methodology Used for Gas Analysis and Control of Trace Chemical Contaminants at a Hyperbaric Facility. 1. Gas Sampling
Abstract
The Naval Medical Research Institute (NMRI) currently conducts human hyperbaric research in a large pressure chamber complex originally installed in 1977. An early incident of organic chemical contamination demonstrated the need for a set of procedures for contaminant analysis, control, and removal that were appropriate for hyperbaric operations. Because such a comprehensive set of guidelines were nonexistent, the development of such methodology was undertaken. This has resulted in the establishment of a gas analysis laboratory in support of diving operations that insures the safety of the chamber atmosphere and gas supply for human diving experiments. This report describes one aspect of this program, that of gas sampling, at the Diving Medicine Department at NMRI. Sampling in this context refers to the collection of gas for subsequent chemical analysis. Because of the large potential for sampling error when working with trace hydrocarbon mixtures, correct gas sampling techniques are extremely important.
