Setting Up a DSC Ramp Procedure


DSC ramp experiments heat or cool the material at a constant rate.  The results obtained are affected by the previous thermal history (often imparted on the material during processing [e.g., extrusion]).  Therefore, the results are designated "as received.

If you want to set up a DSC ramp procedure, you can choose one of two techniquesthe DSC Wizard or the Experimental View - Procedure Page. See the instructions below for each technique.

When you perform a DSC Ramp experiment,  baseline calibration experiment, or cell constant/temperature calibration experiment the following parameters need to be chosen:

You can choose to start your experiment from one of the following choices:

  1. Current Temperaturethe temperature of the DSC cell at the current moment (usually ambient temperature, 30 to 35C). In this case, the ramped heating begins immediately on starting the experiment.

  2. Another Temperatureyou choose the specific temperature desired (default is 50C). In this case, the system equilibrates at the chosen temperature before ramped heating begins.

Using the Experimental View Procedure Page:

  1. Display the Procedure Page. Select the desired experiment from the list of available preprogrammed templates.

  2. Enter the desired parameters. When you have finished setting up this procedure, you can enter more information by selecting the Notes Page and Summary Page for this run.

  3. Click the Apply button when finished to save these changes or the Append  button to save the changes to this run and add another run to the end of the sequence.

NOTE: You can use any test template as the basis for a custom test by selecting the desired test template from the list of tests, then click the Apply button and change the test to Custom. Then you can click on the Procedure Page and then the Editor button to make the changes desired.
