Preliminary Evaluation of a Halogen Leak Detector for Screening Divers' Breathing Air.

摘要

A halogen leak detector underwent a preliminary evaluation to determine if such a device might be suitable for screening divers' breathing air for halogen contamination. Although this instrument is not marketed as a precision analytical instrument, a previous report had concluded that this device was a useful detector for halogenated hydrocarbons. However, current testing of one Ferret indicated that the instrument was nonlinear in response to changing concentrations of several halogens. Because of this characteristic, relative sensitivities would be expected to vary with chemical concentrations. Based on these preliminary data, this leak detector appears unsuitable for simple use in testing breathing air. Keywords: Gas leak detector; Gas analysis; Air purity; Hyperbaric conditions. (KT)
