Autosampler Calibration
The DSC Autosampler may require recalibration to refine pan placement and pickup capabilities. Autos-
ampler calibration involves calibrating the closed cell position, sample loading position, and sample tray
position. These procedures have been automated for ease-of-use operation. You can choose to calibrate all
positions by using the calibration functions from the user interface or from the instrument control program.
Once the Autosampler is correctly calibrated, recalibration is generally required only when you replace the
DSC cell. Periodic checks are the best way of determining when the Autosampler needs recalibration.
Autosampler calibration is accessed through the instrument user interface functions. Consult online help
for detailed instructions.
Running a Discovery DSC™ Experiment
Experimental Procedure
All of your DSC experiments will have the following general outline. In some cases, not all of these steps
will be performed. See the instrument control software online help for anything not covered in this manual.
1
Attach and set up external accessories as required (e.g., purge gas, cooling accessory).
NOTE
: Please make sure that you run your experiments with the same gas used during calibration of the
system.
2
Select and prepare a sample. This involves preparing a sample of the appropriate size and weight, selecting
the pan type and material, and encapsulating the sample in the pan. For details, refer to online help.
3
Load the sample pan (and a similarly prepared empty reference pan) into the cell or onto the
Autosampler tray.
4
Enter experiment and procedure information through the TA Instruments TRIOS Software; this includes
both sample and instrument information.
5
Start the experiment.
Loading the Sample
Once the sample pan has been prepared and the sample information has been recorded, you are ready to
load the sample pan into the DSC cell. The pans will automatically be loaded into the cell by the
Autosampler when you run an Autosampler sequence.
WARNING: If the cell has just been used, the components of the cell could be very hot. As a
safe-operating practice, use the tweezers whenever handling the cell or pans within the cell.
AVERTISSEMENT: Si la cellule vient juste d'être utilisée, ses composants peuvent être très
chauds. Par mesure de sécurité, utilisez des brucelles lorsque vous manipulez la cellule ou les
bassins contenus dans la cellule.
