Tracer Gas Testing
Tracer gas testing involves the release of a non-toxic non-flammable gas into an enclosure, room, building, or environment and the subsequent collection of air samples. Analysis of the samples is completed by gas chromatography. By using a gas not normally found in the earth’s atmosphere, tracer gas methods can be utilized to evaluate building ventilation systems, equipment ventilation systems, airflow patterns, ventilation rates, the ability of an enclosure to contain a gas release or vapors generated from a spill, and contaminant control. The utilization of tracer gas testing in conjunction with other industrial hygiene measurements allows H and H to evaluate a ventilations systems for exhaust re-entrainment, inter-zonal airflow between clean and dirty areas, smoke and contaminant removal, contaminant capture efficiency, make up air supply volumetric requirements, and contamination from outside sources. Evaluations can also be conducted to determine the proper placement of toxic gas monitors, air intake locations, exhaust discharge locations, and the need to physically separate areas.
Equipped with state of the art instrumentation, H and H Safety and Environmental performs a variety of tracer gas testing both on-site and in our laboratory.
Tracer gas testing for the semiconductor industry is performed in accordance with the SEMI F15 standard.
Laboratory fume hood testing is done in accordance with the ANSI/ASHRAE 110 method.
