iGC-SEA Technical Note 807 – Infinite Dilution and Surface Energy Heterogeneity Profile by iGC-SEA

The dilution range of the probes have an influence on the interactions occurring on the surface during inverse gas chromatography measurements. Therefore, careful selection of the injection range is important for every iGC analysis. This paper describes infinite dilution and surface energy heterogeneity measurements and helps to select the right injection range for both types of experiments on iGC-SEA.

iGC-SEA & DVS Application Note 228 –  Water Sorption and Surface Properties of Bathroom Tissues

Bathroom tissues have characteristics that optimise their application to absorb water. Their surface topography enhances their elasticity and maximise their absorbance. These properties modify the surface heterogeneity. With the increasing awareness of the importance to protect the environment, manufacturing companies are developing more environmentally responsible blends of components to create their product. This study compares the surface chemistry of commercially available bathroom tissues and their water sorption uptakes.
