Differential scanning calorimetry (DSC) is a thermo-analytical technique to measure the thermal properties of materials.
It determines the difference in heat required to raise the temperature of a sample and reference as a function of temperature.
Both sample and reference are maintained at nearly the same temperature, with the DSC experiment designed to increase sample temperature linearly over time.
Key Features of DSC
- DSC type: Gas-tight heat flux system
- Temperature range: -170 °C to 600 °C
- Heating/cooling rates: 0.001 K/min to 100 K/min (cooling rate depends on temperature)
- Measurement range: ± 650 mW
- Accuracy: Temperature: 0.1 K; Enthalpy: <1% for metals; <2% for most materials
- Cooling devices: Liquid nitrogen cooling (-170 °C to 600 °C)
- Atmospheres: Oxidizing, inert (static, dynamic)
- Gas control: 3 integrated frits; 3 magnetic valves (programmable)
- Oxidative-Induction Time: Integrated in software
- Accessories: Variety of crucibles (Al, Pt, Al2O3, Au, Ag, Cu, autoclaves, etc.)
- Dimensions: 380 mm × 320 mm × 520 mm; Mass: 28 kg
