Thermal analysis of materials often requires precise measurement of heat flow as a sample follows a controlled temperature program. The Mettler Toledo DSC822e Differential Scanning Calorimeter is a DSC instrument based on the heat-flow principle and developed for differential scanning calorimetry within the Mettler Toledo STARe thermal analysis system. The DSC822e can be used to investigate thermal events by measuring the difference in heat flow associated with a sample and reference during a programmed temperature cycle. Mettler Toledo documentation identifies the DSC822e as a modular instrument with multiple cooling configurations and furnace options, making its configuration dependent on the installed system components.
For analytical laboratories working with thermal characterization, the DSC822e provides high-resolution DSC measurement capabilities. The manufacturer specifies a digital resolution of 16 million points and a ceramic sensor with a 56-point Au-AuPd thermocouple arrangement for the FRS5 configuration. The published technical documentation also specifies temperature accuracy of ±0.2 °C and temperature reproducibility of ±0.1 °C. Depending on the cooling configuration and furnace version, the instrument can support temperature measurements extending to low temperatures and up to 700 °C.
Key Features
- Differential scanning calorimetry based on the heat-flow measurement principle.
- Ceramic measurement sensor with 56 Au-AuPd thermocouple points in the FRS5 configuration.
- 16-million-point digital resolution for the DSC signal.
- Temperature accuracy of ±0.2 °C and temperature reproducibility of ±0.1 °C.
- Modular architecture supporting different cooling options and furnace configurations.
- Published measurement ranges vary with temperature, including ±350 mW at 100 °C, ±250 mW at 300 °C, and ±200 mW at 700 °C.
- Maximum sampling rate of 10 values per second according to Mettler Toledo technical documentation.
Technical Specifications
The DSC822e technical documentation specifies a temperature range that depends on the installed furnace and cooling configuration. Configurations documented by Mettler Toledo include air cooling, cryostat cooling, IntraCooler cooling, and liquid nitrogen cooling. The published maximum temperature is up to 700 °C for applicable configurations, while liquid nitrogen cooling can extend the documented low-temperature range to approximately -150 °C. The FRS5 ceramic sensor uses 56 Au-AuPd thermocouple points and has a published signal time constant of approximately 2.3 seconds with an aluminum crucible. Mettler Toledo also documents a digital resolution of 16 million points and a measurement resolution below 0.04 µW.
The DSC822e was part of the Mettler Toledo STARe thermal analysis platform and is now a discontinued product. Its documented architecture included optional cooling systems, furnace configurations, and automation options. Because configurations can differ, the exact installed accessories and operating range should be confirmed from the individual instrument configuration before purchase or application planning.
Common Applications
Differential scanning calorimetry is used for studying thermal events and material behavior under controlled temperature programs. The DSC822e is therefore relevant to laboratory thermal analysis workflows involving characterization of heat-flow changes, thermal transitions, and related material properties. Documented applications for DSC technology include investigations involving glass transition, crystallization, kinetics, heat capacity, and oxidation induction time; the applicability of a particular method depends on the sample, configuration, and analytical setup.
For laboratories evaluating legacy Mettler Toledo thermal analysis equipment, the DSC822e model designation is important when matching an instrument with existing STARe-based workflows, cooling equipment, furnace configuration, sensors, and other system components. The instrument’s modular design and documented range of configuration options make verification of the specific system configuration an important part of technical evaluation.
