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)
• Nitrogen regulator

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).
2. Use the 7/16-inch wrench to tighten the 1/8-inch Swagelok nut.
3. Attach the nitrogen regulator to the nitrogen supply.

Requirement: The nitrogen must be dry and of high purity (99.997%).

4. Connect the free end of the tube to the collision gas supply.
5. Set the nitrogen regulator to 50 kPa (0.5 bar, 7 psi).
