To install the corona pin in the source:
1. Prepare the instrument for working on the source (see page 5-7 ).
2. Pull the source enclosure release (located at the bottom, right-hand side)
outwards, and swing open the enclosure.
3. Remove the blanking plug from the corona pin mounting contact.
Tip:
Store the blanking plug in a safe location.
Warning:
The LC system connections, ESI probe, and source can
be contaminated with biohazardous and/or toxic materials. Always
wear chemical-resistant, powder-free gloves while performing this
procedure.
Warning:
To avoid electric shock, ensure that the instrument is
prepared for working on the source when commencing this procedure.
Warning:

care while working with the source enclosure open.
Warning:
The ESI probe tip is sharp. To avoid puncture wounds,
take great care while working with the source enclosure open if an
ESI probe is fitted.
