Laboratory hood, Tracer gas, Ethylene, SF6. The environmentally hostile characteristics of SF6 as well as its cost are the major concerns. In this test, sulfur hexafluoride SF6 is applied as a tracer gas to quantitatively evaluate the performance of laboratory hoods. Choosing less environmentally damaging gases for fume hood tracer gas testing. Dale T, Maupins K. The performance of a laboratory ashgae was evaluated using ASHRAE standard method at three different ventilation capacity as well as three different volumetric flow rates of injected SF 6 while a mannequin was located at the front of hood.
