LoginA tracer gas technique has been used for evaluation and characterization of air flow pattern of contaminants penetrating into buildings. As a tracer, sulfur hexafluoride (SF6) was used and detected by a gas chromatograph equipped with an electron capture detector. SF6 was released at suspected points of contaminants origin at a constant flow rate and was detected quantitatively in the room or laboratory of concern.
