Personal Atmospheric Gas Sampler with a Critical Orifice. Part 2 - System for Handling and Analyzing the Gas from the Sampler,

Abstract

A gas handling and analyzing system has been developed to analyze, in the range of 1 ppm, unwanted atmospheric contaminants collected and stored at subambient pressures in a suitable container such as the personal gas sampler developed by NRL for the National Institute for Occupational Safety and Health. One of two subsystems detects individual organic contaminants or, by using a backflush valve, detects the concentration of total hydrocarbons by regrouping the components into one measurable peak. The backflush valve is used also to clean the column after the analysis of individual components prior to subsequent analysis. The other subsystem detects methane and carbon monoxide.
