Differential scanning calorimetry with extremely accurate data. The study of the heat capacity of materials, small thermal effects of phase and chemical transformations
The concept for the DSC 204 F1 Phoenix measuring cell is based on a homogeneous heating of the disc-sensor system for stable and reproducible baselines, also on the effective, low-consumption cooling system.
The DSC measuring cell consists of a cylindrical high-conductivity silver block with an embedded heating coil for broad thermal 3D-symmetry in the sample chamber, the cooling ports for liquid nitrogen or compressed air cooling and a cooling ring for connection of the intracooler, also with simultaneous liquid nitrogen cooling.
The perfect highly efficient and the protective gas flow allow continuous work at low temperatures without frost or ice accumulation in the main body of the measuring cell. The gas-tight construction of the DSC cell enables measurements under very pure, defined gas atmospheres. The precise control and the automated switching of gases is provided by the integrated and calibrated mass flow controller.
The μ-Sensor’s design is based on a specially doped silicon wafer used as a sensor disc. Along with the sensitive temperature sensors, the μ-Sensor offers a level of calorimetric sensitivity that had been considered impossible in DSC until now.
