Cone gas nozzle
Cone gas nozzle handle
Note:
The PEEK handle is removable on earlier models of the cone gas nozzle assembly.
If you detached the handle from the cone gas nozzle for cleaning, replace the handle and
tighten it.
2. Fit the O-ring (a new one, if you disposed of the old O-ring) into the groove created
between the sample cone and cone gas nozzle.
4.12.5 Fitting the sampling cone assembly to the source
Required materials
Chemical-resistant, powder-free gloves
To fit the sampling cone assembly to the source:
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when 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’s tip is sharp).
• A corona pin is fitted (the pin’s tip is sharp).
Notice:
To avoid damage, do not open the source isolation valve before fitting the
sampling cone assembly to the ion block assembly.
1. Ensure that the source isolation valve is in the closed position (see Closing the source
isolation valve (Page 80) ).
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.
