||A tracer method for quantifying contamination of building supply air: reentrainment of laboratory hood exhaust
||Aug. 1983, Vol.44, No.8, p.580-582. 4 ref.
||Sulfur hexafluoride (SF6) used as a "tracer" gas is released in each laboratory fume hood, then detected and measured in the building general fresh-air supply ventilation system. SF6 is quantified with a Miran-1A infrared analyser. Detection limit is in the 13ppb range. Calculations for quantifying reentrainment are presented and discussed.
