Loading Samples into the STA 8000
NOTE: Good quality results require uniform thermal contact between the pans and the
platforms. Avoid spilling sample materials onto the platforms.
Use the following procedure to load samples into an STA 8000:
1. Ensure that the furnace is at a stable temperature below 100 °C.
2. Click the Pause Temperature Control button on the control panel .
This prevents problems with temperature control when the furnace tries to compensate
for rapid changes in heat capacity during sample loading and unloading. If the function
is operating correctly, a short beep is heard every four seconds and the thermometer in
the icon becomes blue in color. If the temperature is above 100 °C or the status of the
instrument is not At Temp, this button is unavailable.
3. Remove the furnace lid using tweezers.
4. Using tweezers, place empty pans on both the reference (right) and sample (left)
platforms.
Ensure that the pans are upright and centered on the platforms.
5. Replace the furnace lid and wait for the weight and temperature to stabilize.
6. Click the Zero Weight button .
7. Remove the furnace lid, and place the sample in the sample pan on the left platform.
It may be easier to remove the pan first to prevent sample being spilled into the
furnace.
8. Replace the furnace lid and wait for the weight and temperature to stabilize.
9. Click the Sample Weight button .
10. Click the Pause Temperature Control button again to restart normal temperature
control.
Two short beeps will be heard, followed by silence.
CAUTION
ATTENTION
Take exceptional care not to drop sample pans or sample material into
the furnace. If this should happen, stop the experiment immediately and
cool the furnace.
Prenez des soins exceptionnels pour ne pas laisser tomber les poêles
d'échantillons ou les échantillons dans le four. Si cela se produit, arrêtez
l'expérience immédiatement et refroidissez le four.
See the software Help for more details of the control panel functions.
