Thermal Analysis: DSC |
The differential thermal analysis (DTA/DSC) serves the measurement of the temperature difference (T) between a sample and an inert sample in function of the temperature (T).
Outstanding features of this DTA/DSC are the newly developed sensitive sensor, the stable base line and high heating- and cooling rates.
There is a good heat transfer between the DSC sensor and the sample crucible, whereas there is a high thermal resistivity towards the sample room. This causes a high sensitivity and low time constants thus enabling an exact determination of enthalphys, specific heat and transformation points.
The bifilar-coil furnaces show an excellent temperature profile thus guaranteeing a very good base line. With cooling rates of 15 min (1400°C to 100°C) these furnaces are also designed for a high sample throughput.
The entire electronics operates digitally and with an own processor system to control and regulate the furnace, the measuring data recording, the gas supply, the vacuum unit and the safety devices. The professional 32-Bit software WinTA 9.0 runs under Windows®98, ME, 2000, NT4.0, XP. An extensive software accurately and efficiently deals with both routine tasks and comprehensive evaluations. Export functions as tables in ASCII and Excel format as well as a graphic file output in the formats BMP, JPG, TIF, EMF etc. enable a cross-platform work.
