Exhaust System

Exhaust System

• Supply a 1-in. i.d. hose to the building exhaust air system, an oil mist filter, or other scrubbing device.
• The pump exhaust contains carrier gas, solvents, analytes, and a small amount of oil vapor.
• These materials may be flammable, poisonous, or corrosive.
• Do not allow the exhaust from the foreline pump, which includes your analytes, to accumulate to unsafe levels in your laboratory.
• Consult your local Environmental and Safety Regulations for information about how to properly exhaust fumes from your laboratory.

Ventilation

Most of the nitrogen that is introduced into the Q Exactive GC escapes into the laboratory atmosphere. Therefore, provide for good air exchange to prevent accumulation of gaseous nitrogen in the laboratory.

Additional Information

• An efficient fume exhaust system is required for the proper operation of your forepump.
• The frequency of the purging is dependent on the throughput of your system.
• Do not route exhaust tubing from the pump vertically toward the ceiling.
• To maintain pump integrity, route the tubing from the exhaust port down to the floor.
• The exhaust hose should travel at floor level for a minimum of two meters (78.5 inches) before it reaches the external exhaust system.
• This tubing acts as a trap for exhaust fumes that would otherwise recondense in the forepump oil.
