HIGH TEMPERATURE CALORIMETRY
DIFFERENTIAL SCANNING CALORIMETRY
COMTES FHT a.s., Průmyslová 995, 334 41 Dobřany, www.comtesfht.cz
Differential Scanning Calorimetry (DSC) is the most popular ther-mal analysis technique for
• research and development • quality management • failure analysis, and • process optimization
It measures endothermic and exothermic transitions as a func-
tion of temperature. Transitions measuremend include Tg, mel-
ting, crystallization, curing and cure kinetics, onset of oxidation
and heat capacity.
TECHNICAL SPECIFICATIONMEASUREMENT PRINCIPLE
LINSEIS High Temperature DSC HDSC PT1600
• Temperature range RT up to 1400 °C
• Heating and cooling rates 0,1 up to 50 °C/min
• Temperature accuracy +/-0,5 °C
• Resolution 0,3 μW
• Atmospheres inert• Vacuum 10-2 Pa• Crucibles Al
2O
3 0,12 ml, Platinum 0,12 ml
The temperature of the sample unit, formed by
sample and reference material, is varied in a spe-
cific program and the temperture difference be-
tween the sample and the reference material is measured as a function of temperature.
APPLICATION EXAMPLES
• Enthalpy, melting energy
• Specific heat• Glass point
• Thermal stability• Oxidation stability
• Purity• Phase transformation
temperature• Solidus/Liquidus relationship
• Eutecticum• Polymorph transformations
