THE ROLE OF HEAT-TRANSFER IN THE PRODUCTION OF DSC CURVES

The influence of heat transfer on heat measurements is discussed and it is demonstrated that the contact between sample and pan, as well as that between pan and heat source, must be maintained constant if reproducible results of heat changes are to be achieved. Where there are difficulties of contact, techniques must be employed which will reduce the possible errors to a minimum. This may necessitate using statistical methods of analysis on a large number of experiments in order to obtain reliable and reproducible results.
