Polymers are typically classified according to their stability and functionality, both of which are engineered to maximize performance.

The ability to measure and quantify this performance is essential for optimizing formulations and advancing development. Polymer surfaces are inherently heterogeneous due to variations in surface topography, organic contamination, and residual unreacted monomers.

These polymers can interact with liquids either through surface interactions (sorption) or through interactions within the polymer bulk (absorption). Solvents and moisture can penetrate into the polymer matrix and cause swelling, leading to significant changes in the surface-area-to-volume ratio.

Changes in the polymer surface can dramatically alter surface area, surface energy, and overall reactivity.

Polymers and Packaging

Determining the diffusion rate at which solvent molecules pass through a polymer is highly important for polymer processing, analysis, and performance evaluation.

Another critical property is the solubility parameter, which is directly related to the cohesive energy density of the material.

The diffusion rate and solubility parameter of polymers can be rapidly and accurately measured by Inverse Gas Chromatography (IGC) across any concentration of solute vapor conditions.

Food and Natural Materials

Solubility parameters are directly related to the cohesive energy density of a material and serve as an indicator of the strength of molecular and atomic interactions.

As such, these parameters can be used to predict the stability of food ingredients. Inverse Gas Chromatography offers a rapid and highly sensitive method for measuring this parameter.
