Differential Scanning Calorimetry (DSC) / Differential Scanning Calorimeter
Differential Scanning Calorimeter (DSC) - Heat Flow measurements from -180°C up to 1750°C
The Differential Scanning Calorimetry (DSC) is the most popular measurement thechnique 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.
Because Linseis has many years of experience in constructing Differential Scanning Calorimeter, we have been able to meet highest demands for each request from research / development and quality controlwith with our DSC PT1000, DSC PT1000 HiRes, DSC PT1000 High Pressure and DSC PT1600 Series in a temperature range from -150°C to 1750°C and a pressure range from vacuum up to 300 bar.
The instrument is used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics. The following interesting physical properties of materials can be measured: Enthalpy, melting energy, specific heat, glass point, crystallinity, reaction enthalpy, thermal stability, oxidation stability, aging, purity, phase transformation, eutectics, polymorphs, product identification, curing and cure kinetics.
The LINSEIS Differential Scanning Calorimeter (DSC) have a unsurpassed performance:
- New Sensor Technology
- Unsurpassed sensitivity – for detection of melts and weak transitions
- Benchmark resolution – precise separation of close lying events
- Reliable Automation – up to 42/84 position autosampler
- 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
- Measurement of thermal / oxidative stability - Determination of OIT (Oxidation Induction Time) in various gas atmospheres and at different pressures.
Possible measurement conditions:
- Temperature range from -150°C to 1750°C
- Various gas atmospheres: air, nitrogen, helium, argon, getter gas, vacuum etc.
- Pressure from 10-5 mbar to 150 bar
