4-68 Maintenance Procedures
• PTFE liner tube
• Conductive sleeve
• Red, PEEK tubing
• Sharp knife
To install the new capillary
1. Use the sharp knife to cut an approximately 60 cm (24 inches) piece of
red, PEEK tubing squarely (that is, perpendicular to its horizontal axis).
2. Insert one end of the red, PEEK tubing in the probe inlet connector, and
screw the connector, finger-tight, into the PEEK union.
Rationale:
Doing so ensures a minimum dead volume when fitting the
capillary.
3. Fit the UNF coupling to the new capillary.
Warning:
The probe and source components can be contaminated
with biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Warning:
The ESI probe tip is sharp. To avoid puncture wounds,
handle the probe with care.
