Surface & Thermal Stability Analysis

Thermal Analysis (TGA / DSC)

Where materials are subjected to controlled temperature environments, G-Hexa reveals how they degrade, transform, crystallize, oxidize, and react. Through high-precision TGA and DSC measurements, we convert thermal transitions into actionable engineering insight for polymers, metals, composites, pharmaceuticals, and advanced materials.

Bridging Thermal Behavior with Real-World Performance

Temperature is not just a variable — it is a stress test of material integrity. Whether evaluating polymer stability, oxidation resistance of alloys, curing behavior of composites, or decomposition kinetics, thermal analysis exposes transitions that determine product reliability.

At G-Hexa, TGA and DSC are not standalone measurements. They are integrated diagnostic tools that reveal:

  • Stability limits

  • Phase transformations

  • Glass transition behavior

  • Reaction mechanisms

  • Moisture and volatile content

By correlating thermal data with process conditions, we bridge laboratory thermograms with manufacturing reality.

ADVANCED THERMAL ANALYSIS CAPABILITIES

State-of-the-art TGA and DSC systems with high sensitivity, programmable heating profiles, and controlled atmospheres for precise thermal characterization.

Temperature Range

Ambient to 1600°C (TGA) and up to 600°C (DSC) with programmable heating rates.

Mass Resolution (TGA)

Microgram-level sensitivity for accurate decomposition and oxidation studies.

Heat Flow Sensitivity (DSC)

High-resolution detection of enthalpic transitions including Tg, Tc, and Tm.

Controlled Atmospheres

Nitrogen, air, oxygen, inert, and reactive gas environments for simulation studies.

Expert Sample Preparation Workflow

G-Hexa ensures reproducible thermal results through controlled sample conditioning, accurate mass calibration, and atmosphere regulation.
  • Sample mass optimization (typically 5–20 mg depending on material type)
  • Pan selection (open, sealed, alumina, platinum)
  • Controlled atmosphere programming
  • Baseline calibration and temperature correction
  • Heating rate optimization for resolution vs. kinetics
  • Repeat validation for data reliability

Challenges in Thermal Analysis

Thermal transitions can overlap, especially in polymer blends, composites, or filled systems. Moisture presence, volatile components, and heating rate variations may distort results.

Our expertise ensures:

  • Accurate differentiation between decomposition and evaporation

  • Reliable Tg detection in complex matrices

  • Correct oxidation onset interpretation

  • Reproducible kinetic modeling

Thermograms are interpreted not as curves — but as mechanistic signatures.

G-HEXA’S VISION — THERMAL INTELLIGENCE FOR INDUSTRY

At G-Hexa, thermal analysis is more than temperature scanning. It is a disciplined investigation into molecular stability, reaction dynamics, and structural transformation. Through data-driven interpretation and industrial correlation, we help industries reduce risk, improve processing efficiency, and engineer thermally resilient systems.

“Every thermogram tells a story — of transformation, stability, and performance under stress.”
