A simultaneous TGA/DSC analyzer — measuring mass loss and heat flow on the same sample at the same time, in three temperature versions.
| Balance type | Horizontal differential (dual-beam) system |
|---|---|
| TG baseline stability (drift) | < 10 µg (heating to 1.000°C, 20°C/min) |
| TG baseline stability (isothermal) | < 10 µg (60 min at 1.000°C) |
| DSC function | Built in as standard (a true DSC signal, not DTA) |
| Specific heat capacity (Cp) measurement | Available as an option, via temperature-modulated DSC (TMDSC) |
| Temperature precision | ±0.07°C |
| Temperature accuracy | ±0.2°C |
| Gas control (MFC) | 2 integrated mass flow controllers (MFC) as standard; option for up to 4 MFCs, with an optional helium MFC |
| Auto-sampler | Optional, four-finger design for automated multi-sample analysis |
| Temperature programs | Continuous heating, heating/cooling cycles, isothermal, TMDSC, Controlled Reaction Rate Thermal Analysis (CRTA) |
| Advanced analyses (software) | Reaction Kinetics Analysis (activation energy, isothermal decomposition time); heating rate conversion |
