Replacing the ESI probe sample capillary
Replace the stainless steel sample capillary in the ESI probe if it becomes
blocked and cannot be cleared, or if it becomes contaminated or damaged.
Removing the existing capillary
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
• 7-mm wrench
• 8-mm wrench
• 10-mm wrench
• Needle-nose pliers
To remove the existing capillary:
1. Remove the probe from the source (see page 61 ).
2. Retrieve the combined 2.5-mm Allen wrench and cone extraction tool
from its storage location on the source adaptor housing.
Warning:
To avoid personal contamination with biohazards or
toxic materials, and to avoid spreading contamination to
uncontaminated surfaces, wear clean, chemical-resistant,
powder-free gloves when working with the probe and source
components.
Warning:
To avoid burn injuries, take great care while performing
this procedure; the probe and source can be hot.
Warning:
To avoid puncture wounds, handle the probe with care;
the ESI probe tip is sharp.
