Setting Up a Conventional MDSC Procedure


The actual complex temperature/time profile in Modulated DSC® depends on three variables—underlying heating/cooling rate, modulation period, and modulation temperature amplitude.  In conventional MDSC experiments, all three variables are operator-selected for best results and the material is evaluated during heating over a temperature range.  

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

As in conventional DSC experiments, MDSC experiments provide valid information only if the material being evaluated is able to follow the temperature profile generated by the instrument.  

When you perform a Conventional MDSC experiment, the following test parameters need to be specified:

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.
