Journal ArticleDOI
Longitudinal diffusion and resistance to mass transfer as causes of nonideality in chromatography
TL;DR: In this article, a rate theory for band broadening in linear, non-ideal chromatography is presented, wherein nonideality is caused by axial molecular diffusion, axial eddy diffusion, and finiteness of transfer coefficient.
Journal ArticleDOI
Sorption nonideality during organic contaminant transport in porous media
TL;DR: In this paper, the relative importance of these factors is scale-dependent and their relative impact on contaminant transport is evaluated for hydrophobic organic compounds, physical nonequilibrium (i.e., rate-limited mass transfer in aggregated or layered systems) and intraorganic matter diffusion (rate-limited diffusion within the sorbent organic matter matrix) are probably the predominant factors causing nonideality.
Journal ArticleDOI
Preparative liquid chromatography.
TL;DR: A survey of the literature dealing with practical applications and recent meetings shows that preparative liquid chromatography is becoming a well established separation and purification method in the pharmaceutical industry as discussed by the authors.
Book ChapterDOI
Analytical gel chromatography of proteins.
TL;DR: This chapter describes the fundamental aspects of gel chromatography as they comprise a set of analytical techniques that a protein chemist may use, and it is evident that the group of techniques based on the partitioning of molecules into porous gel networks constitutes an extremely versatile and useful array of analytical tools for the studies of protein systems.
