Temperature modulated DSC at intermediate-low temperatures
In this paper we present a new cooling system for temperature modulated DSC (TMDSC) working down to about 60 K. In order to demonstrate the features of this new system in combination with commercial TMDSC apparatus, we present measurements of the specific heat capacity (c(p)) around the phase transitions of betaine berate and betaine phosphate. For SilGel 604 we report c(p) and sound velocity data around the melt, as well as around the glass transition.
