The TG-FTIR (Thermogravimetric Analysis coupled with Fourier-Transform Infrared Spectroscopy) system is a state-of-the-art technique designed for detailed thermal investigation of both organic and inorganic materials in solid or liquid states. This integrated solution allows precise evaluation of thermal stability, decomposition patterns, phase transitions, and chemical reactions across a broad temperature spectrum. Nexus Analyticals is your trusted provider and service partner for TG-FTIR systems in India.

TG-FTIR Thermogravimetric Analysis
What you need to know about TG-FTIR Thermogravimetric Analysis?
Why TG and FT-IR Work Together
Thermogravimetric analysis (TG) accurately measures changes in mass during heating, cooling, or other thermal processes, but it cannot reveal the composition of evolved gases. Combining TG with FT-IR spectroscopy bridges this gap, offering real-time identification of gaseous byproducts. FT-IR detects molecular vibrations induced by infrared radiation, generating unique spectral fingerprints for nearly all compounds—except homonuclear diatomics and noble gases—making it ideal for detailed gas analysis.
Key Benefits of TG-FTIR Systems
- Tracks weight and gas together: Monitor mass changes while identifying released gases simultaneously.
- Reliable at any temperature: Whether you’re running hot or cold samples, the equipment gives you solid, repeatable data.
- See reactions unfold in real time: Chemical changes and thermal breakdown don’t happen in a black box—you watch them progress as heating or cooling proceeds.
- Picks up on the subtle stuff: The sensitivity is good enough to catch trace gases and small shifts in the spectra that less refined instruments might miss.
TG-FTIR Coupling Configurations
Modern TG-FTIR systems offer flexible configurations tailored to different laboratory needs:
- External Gas Cell Coupling: Uses a transfer line for versatile, standalone FT-IR operation.
- Internal Gas Cell Coupling: Integrates with the FT-IR sample chamber for efficient, high-sensitivity measurements.
- Direct PERSEUS® Coupling: A compact, streamlined solution combining the FT-IR spectrometer with thermoanalyzers, eliminating transfer lines for fast, high-throughput workflows.
Coupling Options in Detail
External Coupling – Adaptable and Robust
The external module allows switching between standard FT-IR and TG-FTIR modes without compromising performance. Detector options include:
- DLaTGS: Room-temperature detector for routine analysis.
- MCT (Liquid nitrogen-cooled): High-sensitivity detector for trace-level detection.
Internal Coupling – Enhanced Sensitivity
Optimized according to Beer’s Law, internal coupling maximizes gas detection by adjusting the path length and reducing gas cell volume. Advantages include:
-
- Longer path length for stronger IR interaction.
- Compact gas cell for faster response and reduced dilution.
- Suitable for limited sample quantities, making it ideal for both research and QA/QC labs.
PERSEUS® Coupling – Compact and Efficient
The PERSEUS® solution integrates the FT-IR spectrometer directly with the TG system, minimizing gas transfer loss and maximizing efficiency. Key benefits:
- Small footprint, perfect for space-limited labs.
- Rapid response for immediate gas detection.
- Easy setup and low maintenance for streamlined operation.
