Apparatus for differential thermal analysis

摘要

An apparatus comprises a block defining two chambers having openings in the bottom portions thereof. A crucible for a sample is installed in one of the block chambers, and in another chamber there is installed a crucible for a standard material. A baffle is positioned between the sample and the corresponding opening in the block. Between the standard material and the corresponding opening there is also positioned a baffle. Said baffles are made from a material similar to that of the block. The apparatus further comprises two photoelectric pyrometers. The first photoelectric pyrometer is pointed through the corresponding opening at the baffle positioned between the sample and said opening. The second photoelectric pyrometer is pointed through the corresponding opening at the baffle positioned between the standard material and said opening. Recording instruments are electrically connected to the outputs of the photoelectric pyrometers.
