You have to be aware that the TTS analysis does not work if there is crystalization in the temperature range of the experiments. If you give me my email I can share with you some papers of mine that could help you. I don´t know wich instrument are you using but TA Instruments equiments have the TTS analysis and WLF analysis implemented in the software.
I did the experiments using TA instruments but i did the experiments in Australia and the software that i am having do not have the option to do it. My e-mail address is [email protected], [email protected].
