Differential Scanning Calorimeter
Heat Flow measurements from -180°C up to 1750°C
Linseis has many years of experience in constructing DSC (differential scanning calorimeter) equipment. We have been able to meet highest demands for each request from research / development and quality control in a temperature range from -180°C to 1750°C and a pressure range from vacuum up to 300 bar.
Differential Scanning Calorimetry (DSC) is the most popular measurement technique to detect endothermic and exothermic transitions like the determination of transformation temperatures and enthalpy of solids and liquids as a function of temperature. Therefore the sample and reference are maintained at nearly the same temperature throughout the experiment and the heatflux will be measured.
A DSC graph is used to characterize polymers, pharmaceuticals, foods, organic chemicals and inorganics.
Properties to be measured include:
- enthalpy
- melting energy
- specific heat
- glass transition
- crystallinity
- reaction enthalpy
- OIT/OOT
- thermal stability and oxidation stability
- aging
- purity
- eutectics
- polymorphs
- thermochromism
- curing and
- cure kinetics
LINSEIS DSC overview
Applications with Differential Scanning Calorimeter
- Phase transitions – Determination of melting and crystallization points as well as phase transitions by measurement of the change of enthalpy over temperature
- Determination of Glass Temperature – Measurement of TG with high resolution calorimetric detection
- Measurement of specific heat CP – Determination of specific heat CP of solids and liquids with sapphire standard
- Enthalpy measurement of chemical reactions – Determination of endothermic and exothermic enthalpy ΔH of chemical reactions
