Connecting To The Collision Cell Gas Supply - Waters Xevo G2-XS QTof Overview And Maintenance Manual

Nitrogen inlet
2. Attach a nitrogen regulator to the nitrogen supply.
Requirement:
3. Connect the free end of the 6-mm PTFE tubing to the nitrogen regulator.
4. Set the nitrogen regulator to 6.5 to 7.0 bar (94 to 102 psi).
5. Ensure that there are no gas leaks at any of the nitrogen gas supply fittings.
B.5 Connecting to the collision cell gas supply
Required materials
• Chemical-resistant, powder-free gloves
• 7/16-inch open-end wrench
• 1/8-inch Swagelok nut and ferrule
• 1/8-inch stainless steel tube (supplied with the mass spectrometer)
• Argon regulator
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when performing this procedure.
To connect the collision cell gas supply:
1. Use the 1/8-inch Swagelok nut and ferrule to connect the 1/8-inch stainless steel tube to
the collision cell gas inlet on the rear of the mass spectrometer (see the figure in
Connecting to the nitrogen gas supply (Page
2. Use the 7/16-inch wrench to tighten the 1/8-inch Swagelok nut.
3. Attach the argon regulator to the argon supply.
Requirement:
4. Connect the free end of the tube to the collision gas supply.
5. Set the argon regulator to 50 kPa (0.5 bar, 7 psi).
The nitrogen must be dry and oil-free with a purity of at least 95%.
The argon must be dry and of high purity (99.997%).
