B.6 Connecting the nitrogen exhaust line
Required materials
• Chemical-resistant, powder-free gloves
• Utility knife
• Nitrogen exhaust trap bottle
• 4-mm PTFE tubing and 12-mm PTFE tubing (included in the Xevo G2-XS QTof installation kit)
To connect the nitrogen exhaust line:
Warning:
To prevent the escape of exhaust gases into the laboratory, carrying biologically
hazardous, toxic, or corrosive LC solvents, you must use a source exhaust line connected to
either a laboratory fume hood, or to an active laboratory exhaust system. A laboratory exhaust
system must be capable of the following:
• Supporting a gas load of up to 2000 L/hour.
• Periodically draining off any liquid solvent that accumulates in the exhaust lines.
• Maintaining a pressure below atmosphere, no lower than -1 kPa (-10 mbar, -0.145 psi).
Warning:
trap bottle in an enclosed cabinet.
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when performing this procedure.
Notice:
are required: one for nitrogen, the other for the roughing pumps. Vent the exhausts to
atmosphere through separate lines. Oil mist can seriously damage the instrument if the
nitrogen exhaust line connects with the roughing pump exhaust line. Your warranty
does not cover damage caused by routing exhaust lines incorrectly.
1. Locate the nitrogen exhaust trap bottle in an accessible area below the instrument.
To avoid the buildup of hazardous gases, do not place the nitrogen exhaust
To prevent serious damage to the instrument, two separate exhaust systems
