Inverse Gas Chromatography
Inverse gas chromatography (IGC), which allows the measurement of surface properties of solids (powders, polymers, fibres, pigments, carbons, mineral oxides, API, excipients, etc.). This technique allows for example to compare batches (quality control), but also to study the influence of ageing, the effect of grinding, the effect of surface treatment (chemical, thermal, coating) or to follow the evolution of the surface according to storage conditions.
Depending on the type of sample (powders, fibres...) sample (g to about 10 g).
MSDS sheets must be provided if available.
Information such as BET surface and grain size should be provided (if known).
