Characteristics
- Options
- differential, high-temperature, differential scanning, high-sensitivity, with auto-sampler, DSC, vacuum-tight, heat-flow, automated, for gas
Description
- Simultaneous Thermal Analysis (STA) combining thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) in a single instrument for comprehensive thermal and compositional characterization of materials.
- Suitable for polymers, life-science materials, inorganics and general materials testing (QC, R&D, failure analysis).
- Vacuum-tight design with options for defined atmospheres and coupling to evolved gas analysis systems.
Highlights
- Temperature range (sample): approx. 10 °C (RT) to 1,025 °C standard; options up to 1,100 °C.
- Water-cooled ceramic furnace enabling fast heating and controlled cooling.
- Top-loading microbalance with 20 ng resolution and wide mass range up to 2,000 mg.
- Ring sample holder design that eliminates the need for a conventional reference crucible and reduces setup time.
- Interfaces for coupling to QMS, FT-IR and GC-MS via heated transfer lines for real-time evolved gas identification to ppm sensitivity (analyzer-dependent).
- Optional magnetic shock absorbers to reduce external vibration influence and improve reproducibility.
- High-capacity automation: Automatic Sample Changer (ASC) microplate format (two interchangeable trays, 96 positions each) and calibration/correction strip for up to 12 crucibles.
- Optional piercing device for sealed crucibles to analyse volatile or unstable samples automatically before measurement.
- Local color touch display for basic operation and monitoring without PC; Proteus software for full control and evaluation.
- Eco Mode (software) to reduce chiller and gas consumption during idle phases; LabV-ready for integration with centralized material-intelligence platforms.
Measuring principle
- Sample preparation: small sample amounts in suitable crucibles (various materials/volumes available).
- Heating/cooling: controlled temperature programs (ramps, steps).
- Simultaneous measurement: TGA records mass changes while DSC measures heat flow; combined data enable analysis of decomposition, oxidation/reduction, phase transitions, glass transitions, curing and heat capacities.
Evolved Gas Analysis (EGA)
- Designed for coupling to QMS, FT-IR and GC-MS via heated transfer lines or heated fused-silica capillaries.
- Enables correlation of mass/heat events with identified gas species during TGA/DSC experiments.
Software & Data Analysis
- Proteus — instrument control, data acquisition and reporting.
- AutoEvaluation — automatic detection and evaluation of TGA/DSC events (mass steps, DTG, peak temperatures, endo/exothermic signals).
- Identify — searchable material-identification databases (NETZSCH libraries) with user extendable entries.
- Kinetics Neo — advanced kinetic modelling for multi-step decomposition and predictive simulations.
- Report generator, search engine, peak separation tools and automated specific heat capacity (cp) calculations according to standards (e.g. ASTM, DIN).
Accessories & Automation
- Automatic Sample Changer (ASC) with two removable 96-sample trays (microplate format) and an additional calibration strip for up to 12 crucibles.
- Piercing device for sealed crucibles to allow automated analysis of volatile samples when used with the ASC.
- Wide selection of crucible materials and volumes (ensure chemical compatibility with samples).
- Optional magnetic shock absorbers to minimise vibrational noise and improve reproducibility.
Technical specifications
- Temperature range (sample): ≈ 10 °C (RT) to 1,025 °C standard; optional to 1,100 °C.
- Balance resolution: 20 ng.
- Mass range: up to ≈ 2,000 mg.
- Heating/cooling rates: approx. 0.001 K/min to 300 K/min (configurable).
- Fast cooling example: in N2 ≈ 12 min from 1,100 °C to 100 °C; in He ≈ 5 min to 100 °C (≈10 min to RT).
- Vacuum-tightness: << 10⁻¹ mbar (vacuum-capable design).
- Sample crucible volume: up to ≈ 300 µL (dependent on crucible type).
- TGA accuracy: approx. 0.0003% (instrument- and method-dependent).
- DSC accuracy: approx. ±5% (instrument- and method-dependent).
- Coupling capability: heated transfer lines to QMS, FT-IR and GC-MS; detection down to ppm depending on analyzer.
- User interface: color touch display; full control & evaluation via Proteus software.
- Energy & sustainability: Eco Mode to reduce chiller and gas consumption during idle periods.
