Use of an Analog to Improve the Performance of a Differential Thermal Analysis Apparatus

Abstract

Both passive and active analogs have been used to investigate the effect of holder design on the shape of DTA peaks. To produce minimum distortion of the peak shapes it has been found that the holder must have the following properties: a high heat capacity compared with the sample and reference material; a high diffusivity so as to pass heat rapidly to the reference and sample materials; it must also effectively isolate the reference and sample materials. © 1968, American Chemical Society.
