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
