Dynamic differential calorimetry
Heat Flow measurements from -180°C up to 1750°C
The Differential scanning calorimetry or Differential Scanning Calorimeter (DSC) is a very widely used method for determining transformation temperatures and enthalpy changes of solids and liquids under controlled temperature changes.
The functional principle is the measurement of the heat flow between the sample and a reference.
This is done via a defined heat conduction path.
The heat flow is recorded as a function of an external temperature change.
Our many years of experience have enabled us to develop a range of differential calorimeters – the Linseis Chip-DSC 10, Chip-DSC 100 and DSC PT1600 – to meet every requirement in research / development and quality control in a temperature range from -180°C to 1750°C and under pressures of up to 150 bar.
The analyzer is used for the characterization of polymers, pharmaceuticals, foodstuffs as well as organic and inorganic substances.
Properties to be measured include:
- Tg – Glass point
- Melting point
- Crystallization
- Phase transformation
- Curing (hardening)
- Curing kinetics
- Thermal stability and oxidation stability
- Ageing processes
- Purities
- Specific heat (Cp) and thermochromism
LINSEIS DSC overview
Properties
- Phase transformations – determination of melting and crystallization points, as well as phase transitions by measuring the enthalpy change against temperature.
- Glass point determination – measurement of the TG by high-resolution caloric detection.
- Measurement of the specific heat capacity Cp – Determination of the spec. heat capacity Cp of solids and liquids using sapphire reference measurement.
- Enthalpy determination of chemical reactions – Determination of the endothermic and exothermic enthalpy of reaction ΔH for chemical reactions
- Measurement of thermal / oxidative stability – Determination of the OIT (Oxidation Induction Time) under different gas atmospheres and pressures
Possible measurement conditions of our DSC´s
- Temperatures from -180°C to 1750°C
- Various gas atmospheres: Air, nitrogen, helium, argon, forming gas, vacuum, etc.
- Pressure from 10-5 mbar to 150 bar
All LINSEIS Differential Scanning Calorimeters (DSC) operate in accordance with the following national and international standards ASTM C 351, D 3417, D 3418, D 3895, D 4565, E 793, E 794, DIN 51004, 51007, 53765, 65467, DIN EN 728, ISO 10837, 11357, 11409.
