Abstract:
A cooling-heating stage-type fast scanning calorimeter capable of being integrated with other microscopic structure characterization techniques. The cooling-heating stage-type fast scanning calorimeter includes a sample chamber provided with light transmission and reflection transparent windows on the walls thereof, a cooling-heating stage provided with internal heating elements and coolant channels for temperature control and also provided with a transmission hole, a sample chamber temperature control system and a fast calorimetric system. The cooling-heating stage-type fast scanning calorimeter has the advantages that the fast calorimetric system with heating/cooling rates is miniaturized into the cooling-heating stage, and reflection and transmission windows as well as the transmission hole of the cooling-heating stage are used for in-situ integration of calorimetry and microscopic structure characterization; and through program-controlled rapid response, dynamic compensation of sample temperature disturbances caused by incident light in structure measurement is achieved, and sample temperature is stabilized, thus facilitating precise isothermal research.
