Hello everyone,
can anyone help me to calculate the specific heat capacity of a sample by using the TA Instruments software TRIOS? I have done three experiments as described in the ASTM E1269 standard using DSC Q20 which operates with Advantage software. I have opened the three files in TRIOS but the option to calculate Cp in the "Transformations" menu is missing, there is only "Reduce" and "Merge". Can anyone tell me why this is happening and how to solve this problem?
Hi Vlado,
I would recommend to address your question directly to the TA Instruments' people:

Hello,
When performing the 3 run heat capacity measurement in TRIOS, the Sapphire sample must be named "Sapphire" and the baseline sample must be named "Baseline" and then your sample of interest can have any name. If the sapphire and baseline samples are not named exactly as prescribed, the machine doesn't know which sample is which. Also, all the samples must be run under identical conditions. Usally the sample method starts with an equilibration at a specific temp followed by data on, followed by 10 min isothermal, followed by 20c/min ramp, followed by 10 minute isothermal, and then data off. When doing the 3 run heat capacity transformation, be careful not to accidentally select merge, if you merge any of the segments of the thermogram, the software will no longer recognize that sample as compatible with the others. If that happens you will need to remove the step that got merged with the ramp portion of the run.
Thanks for the comment and tips Travis Moller! I will take them into account for determining the specific heat capacity.
