Royal Society of Chemistry

Particle Characterisation Interest Group

The Particle Characterisation Group (PCIG) provides a forum for anyone with an interest in dimensionally characterising single or assemblies of particles to meet to exchange views, discuss problems and generate ideas. It brings together diverse but interdependent specialists from many industries to provide a link between different industries and educational institutions.

Membership embraces chemists, physicists, pharmacists, engineers (chemical, mechanical and civil), and many other scientific disciplines concerned with solving the process problems that occur when size, shape, and/or distribution of particles changes or varies.

Frequent meetings of the PCIG are held on a friendly and informal basis to encourage the free exchange of ideas and to promote lively discussion.
