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 88 ).

4. Fit the blanking plug to the corona pin mounting contact (see the figure
on page 94 ).
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.

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.
