4.12 Cleaning the source components
Clean the sample cone and cone gas nozzle when these conditions apply:
• The sample cone and cone gas nozzle are visibly fouled.
• LC and sample-related causes for decreased signal intensity are dismissed.
See
Cleaning the sampling cone assembly
.
If cleaning the sample cone and cone gas nozzle fails to increase signal sensitivity, clean the ion
block and isolation valve (see
Cleaning the ion block assembly
).
If cleaning the ion block and isolation valve fails to increase signal sensitivity, clean the StepWave
assembly (see
Cleaning the StepWave ion guide assembly
).
4.13 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.
