There has been enlarged importance on health and safety of laboratory workers and as well as environmental concerns. In recent years, Government set stringent condition to control emission from exhaust from laboratories. Testing in research laboratories often generates vapors, acids, solvents or VOCs. The vapor produced can be low concentration. However, the vapor will be accumulated over the period of time and often disperse in low-lying areas, there by increasing the concentration above the Permissible exposure Limit and IDLH. Hence it is required to capture toxic gases coming from test vessels and filter before releasing into the room.
