Thermal Analysis: DTA
|
|
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).
The sensitive sensor and the homogeneous temperature profile are excellent features of this DTA/DSC.
There is a good heat transfer between the DSC sensor and the sample crucible, whereas there is a high thermal resistivity towards the furnace room. This causes a high sensitivity and low time constants thus resulting in an exact determination of enthalphys, specific heat and transformation points.
The disc-shaped furnace shows an excellent and homogeneous temperature profile guaranteeing a straight and flat base line.
The entire electronics operates digitally and with an own processor system to control and regulate the furnace, the measuring data recording, the gas supply 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.
