GAS DETECTOR AND ANALYZER

摘要

A portable, self-contained gas detector and analyzer is disclosed which includes a carrier gas supply, and electrical power supply, a sampling loop and a chromatographic column with an electron-capture detector. A preferred embodiment is adapted to respond to a pre-selected tracer gas. If the tracer is included in a closed system whose integrity is suspect, the detector can first be operated to detect the presence of the tracer and then can signal the rate at which the tracer is being provided to a predetermined, limited volume.
