Notice:
Do not fill the pump beyond the “max” mark.
15. Refit the oil inlet plug.
4.11 Cleaning the source components
Clean the sample cone and cone gas nozzle when the following conditions apply:
• The sample cone and cone gas nozzle are visibly fouled.
• You dismissed LC and sample-related causes for decreased signal intensity.
If cleaning the sample cone and cone gas nozzles fails to increase signal sensitivity, also clean
the ion block and isolation valve (see
Cleaning the ion block components (Page 103)
If cleaning the ion block and isolation valve fails to increase signal sensitivity, also clean the ion
guide assembly (see
Cleaning the ion guide assembly (Page 111)
).
4.12 Cleaning the sampling cone assembly
You can remove the sampling cone assembly (comprising the sample cone, O-ring, and cone gas
nozzle) for cleaning without venting the instrument.
4.12.1 Removing the sampling cone assembly from the source
Required materials
Chemical-resistant, powder-free gloves
To remove the sampling cone assembly from 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 harmless, static-like electric shock, before you touch any external
surfaces marked with the high-voltage warning symbol, ensure that the mass
spectrometer is in Standby mode.
