New method of correction of chromatographic curves for instrumental widening

Determination of pore volume distribution from size exclusion chromatography data

“…Recently, works dealing with the application of size exclusion chromatography to the study of the pore structure of solid materials have been reported (1)(2)(3)(4)(5)(6). A straightforward method of obtaining porosimetric information from chromatographic data had been proposed by Halász and co-workers (1-3).…”

“…Another weak point of this approach is the supposition about the monomodal shape of pore distribution, built into the basic equation. Vilenchik and co-workers (6) proposed the solution for the general shape of distribution but their method is also based on transformation of experimentally determined Ve to K.…”
