Addition information: dispersive component of surface energy, acid-base properties, Tg (glass transition temperature) of polymer films, adsorption isotherms, morphology indices (nano-roughness)
Experience level of provider: very high. Sensitive and versatile method, broad experience over 30 years
Service level: dedicated laboratory and experienced key person with 15 years experience initially during PhD
Application fields:
Nano-materials: carbon nanotubes, nano-clays, nano-silicas, use in composite materials
Pharmaceuticals: polymorph characterization, drug-carrier interaction for dry powder formulation, triboelectric charging, differentiate crystalline/amorphous phases
Fibers: textiles, natural fibers, glass fibers, carbon fibers, fibers in composites, explain via adhesion and cohesion
Polymer particles: polymer films, beads and powders
Others: paper-toner adhesion, wood composites, porous materials, food materials
Description in Wikipedia: http://en.wikipedia.org/wiki/Inverse_gas_chromatography
Alternatives: contact angle methods. Difficult for particles and fibers since flat surface is required and pressed samples behave differently. Alternatively, Washburn method capillary rise) may be used, but accuracy is low.
