Our Techniques
Pioneering the future of material characterization. Our advanced instrumentations are built upon two powerful experimental techniques: Dynamic Vapor Sorption (DVS) and Inverse Gas Chromatography (iGC). Discover how these methods provide unparalleled insights into material properties.
Dynamic Vapor Sorption (DVS)
Precision measurement of moisture and vapor interactions in solids.
Developed over 30 years ago by Prof. Daryl Williams, DVS is a gravimetric sorption technique that quantifies how a material’s mass changes when exposed to controlled humidity or vapor environments.
By tracking microgram-level weight changes in real time, DVS reveals isotherms, kinetics, hysteresis, and moisture-induced transitions that directly impact product stability and performance.
Key Capabilities
- Microbalance resolution up to ±0.1 μg
- Full programmable RH control (0–98%)
- Optional organic vapor sorption capability
- Temperature control up to 85°C
- Outputs: Isotherms, Kinetics, Hysteresis, Transition points

Inverse Gas Chromatography (iGC)
Measuring surface interactions with unmatched precision.
iGC is a gas-phase analytical technique that measures the surface energy of powders, fibers, and particulates. It quantifies dispersive, specific energies, acid-base parameters, and surface heterogeneity, helping researchers understand adhesion, cohesion, and compatibility between materials.
Key Capabilities
- Dispersive surface energy (γd) & acid–base parameters (Ka / Kb)
- Work of adhesion & cohesion
- BET surface area via n-alkane series
- Energetic heterogeneity profiling
- Infinite and finite dilution modes

Breakthrough Analysis (BTA)
Dynamic adsorption testing for gas separation and purification materials.
Breakthrough Analysis is a dynamic flow technique that measures how adsorbent materials capture gases under realistic process conditions. By flowing a gas mixture through a packed bed and monitoring the outlet concentration, BTA determines adsorption capacity, selectivity, and kinetics.
This technique is essential for evaluating materials used in carbon capture, gas purification, air separation, and environmental remediation applications where real-world performance matters.
Key Capabilities
- Multi-component gas mixture analysis
- Dynamic adsorption capacity measurement
- Breakthrough curve profiling and analysis
- Temperature and pressure cycling (TSA/PSA simulation)
- Outputs: Breakthrough curves, Capacity, Selectivity, Cycle stability
