Molecular Fingerprint & Functional Group Intelligence
Fourier Transform Infrared Spectroscopy (FTIR) Analysis
From Infrared Absorption to Chemical Clarity
Every material carries a molecular fingerprint. Functional groups absorb infrared radiation at characteristic frequencies, revealing chemical composition, bonding environment, and structural changes.
At G-Hexa, FTIR is not simply peak matching — it is structured chemical interpretation that reveals:
Polymer type and formulation
Additives and fillers
Oxidation and degradation pathways
Surface contamination
Curing and crosslinking behavior
By correlating spectral data with processing conditions and performance outcomes, we bridge laboratory spectroscopy with industrial chemistry.
ADVANCED FTIR CAPABILITIES
High-sensitivity FTIR systems with multiple sampling modes for solid, liquid, thin film, and powder analysis.
ATR-FTIR Analysis
Rapid surface-sensitive identification with minimal sample preparation.
Transmission Mode
High-resolution analysis for thin films and transparent samples.
Reflectance (DRIFTS)
Diffuse reflectance analysis for powders and rough surfaces.
Micro-FTIR Mapping
Spectral Library Matching
Quantitative Analysis
Expert Sample Preparation Workflow
- Selection of optimal measurement mode (ATR, transmission, reflectance)
- Thin film preparation or KBr pellet method (if required)
- Surface cleaning to eliminate contaminants
- Controlled pressure application in ATR mode
- Baseline correction and atmospheric compensation
- Repeat spectral validation
Challenges in FTIR Analysis
Overlapping peaks, moisture absorption, and surface contamination can complicate interpretation. Complex polymer blends or multi-component systems may produce congested spectra.
Our expertise ensures:
Accurate functional group assignment
Differentiation between similar polymer families
Identification of oxidation, hydrolysis, and degradation products
Reliable interpretation of subtle spectral shifts
Spectra are interpreted chemically — not just computationally.

TRAINED INTERPRETATION, CHEMICAL INTELLIGENCE
Material Identification
Degradation & Oxidation Analysis
FROM FAILURE INVESTIGATION TO FORMULATION DEVELOPMENT
FTIR supports both diagnostic and developmental objectives:
Polymer degradation studies
Coating adhesion failure analysis
Additive compatibility evaluation
Counterfeit material identification
R&D formulation validation
Each spectrum contributes to chemical transparency and product reliability.
MOLECULAR INSIGHT FOR INDUSTRIAL PRECISION
FTIR is more than spectroscopy — it is molecular intelligence. Every absorption band carries structural meaning, and every spectrum holds the chemistry behind performance. Through disciplined spectral interpretation and industrial correlation, we convert vibrational data into chemical certainty.
