The Treatment of Thermoanalytical Data for Effective Presentation
Techniques to facilitate extraction of the maximum meaningful information from thermoanalytical experiments are considered. Attention was given to the collection, manipulation and presentation of observations from DTA and TG. Off-line manipulative routines are assessed to provide smoothing, temperature linearisation, scaling, interpolation and differentiation of digitised analogue signals. The presentation of data to facilitate recognition and interpretation curve features is examined. The form of the manipulated data allows for the averaging of observations from repeated experiments to reflect representative behaviour. DTA curve corrections to eliminate the distorting influences of base lines are also facilitated.
