## Abstract Simultaneous use of large standard molecules and small particles of the product examined gives rise to errors in pore size determination by size exclusion chromatography. This error is calculated for packings of spherical particles, thus making corrections possible.
The pore-size distribution of activated carbons in the range of openings below 13 nm has been determined by liquid chromatography (LC). The initial stage of work involved the choice of a suitable solvent and of working conditions ensuring operation within the region of Henry's law. Dimethyl fo rmami
The problem of extracting pore size distributions from characterization data is solved here with particular reference to adsorption. The technique developed is based on a finite element collocation discretization of the adsorption integral, with fitting of the isotherm data by least squares using re
