Removing the corona pin from the source
Required material
Chemical-resistant, powder-free gloves
To remove the corona pin from the source:
1. Prepare the instrument for working on the source (see page 97).
2. Pull the source enclosure release (located at the bottom, right-hand side) outward,
and swing open the enclosure.
3. Remove the corona pin from its mounting contact (see the figure on page 103).
Tip: Store the corona pin in a safe location.
4. Fit the blanking plug to the corona pin mounting contact (see the figure on
page 102).
5. Close the source enclosure.
Warning: To avoid personal contamination with biologically hazardous, or
toxic materials, and to avoid spreading contamination to uncontaminated
surfaces, wear clean, chemical-resistant, powder-free gloves while performing
this procedure. The LC system connections, ESI probe, and source can be
contaminated.
Warning: To avoid electric shock, ensure that the instrument is prepared for
working on the source before commencing this procedure.
Warning: To avoid burn injuries, take great care while working with the
instrument’s source enclosure open; the source can be hot.
Warning: To avoid puncture wounds, take great care while working with
the source enclosure open if an ESI probe is fitted; the ESI probe tip is sharp.
