B-12 External Connections
Connecting to the nitrogen gas supply
Required materials
• Chemical-resistant, powder-free gloves
• Sharp knife
• Wrench
• 6-mm PTFE tubing (included in the Waters Rough Pump Connect Kit)
• Nitrogen regulator
To connect the nitrogen gas supply:
1. Use the sharp knife to cut a 3.8-cm to 5.0-cm (1.5-inch to 2-inch) length
of 6-mm PTFE tubing.
2. Connect this piece of tubing to one end of the nitrogen supply in-line
filter.
3. Connect the remaining length of the 6-mm PTFE tubing to the other end
of the filter.
4. Connect the free end of the short piece of 6-mm PTFE tubing to the
nitrogen inlet port on the rear of the instrument.
Caution:
To avoid gas leaks, use the sharp knife to cut the PTFE tubing
squarely (that is, perpendicular to its horizontal axis).
