Guidelines for Maintaining the Autosampler
Routine Maintenance and Inspection
Carry out the following tasks regularly to avoid problems.
•
Use only degassed and filtered HPLC grade solvents for the flushing solution.
•
Make sure the flushing solution container is clean and rinse it out with fresh solvent
before filling.
•
Do not let the waste container overfill. Empty it regularly, ensuring the solvent is disposed of correctly.
•
Check the filters regularly, and clean or replace them as required.
•
Check the system regularly for leaks. Where necessary, tighten joints or replace damaged parts.
•
If you do not run solvent through the Autosampler for a period of 24 hours, flush the
sample and flush pump syringes, and the tranfer tubing, with isopropanol before running any samples.
Viewing the Instrument Log
Periodically check the Instrument Log as described in section “Viewing the Instrument Log”
in Chapter 6 of this manual. This lists the number of valve and injection cycles performed
by the Autosampler. You can use this information to help set up a maintenance schedule.
Warning
Before starting any maintenance work:
1. Switch off all instruments in the system.
2. Disconnect the Autosampler from the electrical supply.
3. Follow the maintenance instructions
exactly as described in this chapter.
