Differential Scanning Calorimeter (Perkin Elmer Diamond)
The IFM research group has two types of Differential Scanning Calorimeters, heat flux (Netzsch) and power compensating (Perkin Elmer). These units are essential for the study of decomposition, phase change and melting points or metals and polymers.
Perkin Elmer Diamond DSC
- DSC type: Power-compensation temperature null principle. Measures temperature and energy directly, rather than differential temperature (DT).
- DSC cell: Independent dual furnaces constructed of platinum-iridium alloy with independent platinum resistance heaters and temperature sensors with furnace mass less than 1g.
- Temperature sensors: Distributed platinum resistance thermometers for best linearity.
- Atmosphere: Static or dynamic, including nitrogen, argon, helium, carbon dioxide, air, oxygen or other inert or active gases, over full temperature range. Oxygen can be used up to 730°C which allows easy cleaning.
- Temperature range: -170°C to 730°C.
Accuracy / Precision ±0.1°C / ±0.01°C
- Calorimetry: Accuracy / Precision <±1% / <±0.1%
Dynamic range 0.2µW to 800mW
- Isothermal digit (10 min)-150°C / 100°/c < 15 µW / < 10 µW
- Scanning rates: Heating / cooling 0.01°C to 500°C/min
- Temperature overshoot: 100°C/min<0.1°C
- Cooling times: Ambient coolant 725°C to 100°C (under 4 minutes)
- Liquid N2 coolant: 200°C to -150°C (under 2 minutes)
