Diffusion, adsorption and catalytic studies by gas chromatography

Three topics important in many areas of physical chemistry, namely measurements of diffusion coefficients, adsorption kinetics and adsorption isotherms, as well as rates and conversions in heterogeneous catalysis, are reviewed from the gas chromatography viewpoint. After a general introduction, various theoretical sections include synopses of important mathematical models and developments, followed by experimental sections describing basic instrumentation and set-ups, and sections exemplifying the main results with brief discussions. The article is concluded with a methodology embracing simultaneous determination of all three properties (diffusion, adsorption and catalytic rates) in a single experiment by GC.
