Cleaning the sampling cone assembly 5-37
To fit the sampling cone assembly to the source:
1. Ensure that the source isolation valve is in the closed position (see
page 5-14 ).
2. Hold the sampling cone assembly so that the cone gas nozzle handle is
oriented horizontally and at the top, and then slide the sampling cone
assembly into the ion block assembly.
Warning:
The source components can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Warning:
To avoid puncture wounds, take great care while working with
the source enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe tip is sharp).
• A corona pin is fitted (the pin tip is sharp).
Caution:
To avoid damage, do not open the source isolation valve before
fitting the sampling cone assembly to the ion block assembly.
