Maintenance
3. If there are particles in the rinsing liquid they can lodge in the valves, causing
leaks and non-reproducible results.
4. Empty the waste bottle. Dispose of any hazardous waste correctly.
5. Fill and flush the system:
•
In the
Furnace Control
window, click on
Flush Sampler
. This activates
a special rinse cycle.
•
Repeat substep 1 as often as required to completely fill the rinsing system
with rinsing liquid and to flush out all the air.
6. If you want to use a different rinsing liquid to that already in the rinsing system,
rinse all traces of the previous liquid out of the rinsing system. Use a rinsing
liquid that is miscible with both the new and the old rinsing liquids.
You may have to use intermediate rinsing liquids.
For example, if you are changing from an acidic liquid to an organic solvent,
you could use:
•
Deionized water,
•
Isopropanol or other water-miscible solvent,
•
Final organic solvent.
Valve Maintenance
The autosampler pumps dispense microliter volumes of liquid with high precision.
To maintain this high precision it is essential that the valves function correctly. If
there is a deterioration in the precision of the analytical results, and other sources
of error can be excluded, this is an indication that a valve may not be functioning
correctly.
Only the rinse pump contains valves. The sample pump contains inserts that are a
similar shape to the rinse pump outlet valve.
Note
Make certain there are no air bubbles in the rinsing system. Air bubbles can
lead to non-reproducible results.
