What factors shoud be considered for determining the appropriate exhaust system for the Q Exactive GC?
Q Exactive GC
- 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.
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.
- 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.
