Graphite Furnace Maintenance for the PinAAcle 900T/900Z
3. Click on
Start
to heat the furnace.
The furnace is heated to the selected temperature and continues to heat until
you stop it.
4. After about 10 seconds, click on
Start
again to stop furnace heating.
Checking and Cleaning the Furnace Windows
The quartz furnace windows seal the ends of the furnace where the radiation
beam enters and exits.
Over a period of time sample constituents can accumulate on the windows. This
reduces the intensity of the radiation and the sensitivity and precision of the
analytical results.
Remove the windows and clean them regularly. How frequently depends on the
type of samples that are being analyzed.
If you analyze samples that have ‘dirty’ matrices, such as blood, sugar and oil,
you will probably have to clean the furnace windows more often than if you
were analyzing ‘clean’ samples, such as drinking water.
To Remove the Windows
1. Make sure that the furnace is cool.
2. Carefully swivel the furnace autosampler out of the way.
3. Tilt the furnace forward (see
Tilting the Graphite Furnace Back Into Position
).
4. Use the key provided to unscrew the left-hand and the right-hand windows
from the furnace.
Caution
Risk of damage to the furnace windows
•
The quartz windows are precision optical components; handle them
carefully to prevent scratches, fingerprints or other contamination.
