Maintaining The Source Block Assembly - Thermo Scientific Surveyor MSQ Plus Hardware Manual

Maintaining the Source Block Assembly

Thermo Scientific
The entrance cone is the only component of the source block assembly that requires frequent
cleaning. The cone wash nozzle rarely requires cleaning because it is used to spray the entrance
cone with cleaning solvent.
Note When it is not in use, ensure that the cone wash nozzle faces away from the entrance
cone. See Figure 62 on
You do not need to disassemble the source block assembly to clean the entrance cone and the
cone wash nozzle. To clean the RF/dc prefilter, the extraction cone, or the source block itself,
you must remove the source block assembly from the MS detector and disassemble it.
To clean any or all of the components of the source block assembly, follow these procedures:
1. Preparing the LC/MS System for Maintenance
2. Clearing Access to the Source Block Assembly
3. Removing the Entrance Cone and the Cone Wash Nozzle
4. Cleaning the Entrance Cone and the Cone Wash Nozzle
5. Removing the Source Block Assembly
6. Cleaning the RF/dc Prefilter
7. Cleaning the Extraction Cone and the Source Block
8. Assembling the Source Block Assembly
9. Installing the Source Block Assembly
CAUTION Wait for the source block and probe heater assembly to cool before carrying out
any maintenance.
