Abstract
Size exclusion chromatography (SEC) is the most widely used method for aggregation analysis of pharmaceutical proteins. However SEC analysis has a number of limitations, and one of the most important ones is protein adsorption to the resin. This problem is particularly severe when using new columns, and often column preconditioning protocols are required. This review focuses on the role that addition of various cosolvents to the mobile phase plays in suppressing that protein adsorption. Cosolvents such as salt, amino acids, and organic solvents are often used for this purpose. Because the protein interaction with the resin surface is highly heterogeneous, different cosolvents affect the protein adsorption differently. We will summarize the various effects of cosolvents on protein adsorption and retention and describe the mechanism of the cosolvent effects.

Abstract
Magnetic resonance imaging (MRI) techniques have been implemented to enable quantitative imaging of protein and urea within a 5 ml HiTrap size-exclusion chromatography desalting column, without introduction of contrast agents. One-, two- and three-dimensional images of urea injected at concentrations of 2, 4, 6 and 8 M were acquired. One-dimensional profiles of lysozyme at concentrations between 5 and 25 mg ml(-1) were also obtained. All data were accurate to within +/- 15% when compared to the known amount injected. Quantitative MRI elution profiles of both urea and lysozyme were then obtained in real-time during a desalting separation.

Abstract
Currently, the selection of a hydrophobic interaction chromatography (HIC) sorbent for protein separation purposes is entirely based on empirical means. An attempt was made to characterize different HIC sorbents from various manufacturers. The selectivity was determined by isocratic pulse experiments of a set of reference proteins and an algorithm was developed to classify the sorbents according to their selectivity and hydrophobicity. The obtained semi-quantitative parameters take into account the dependence of salt on adsorption. The sorbent characteristics evaluated with the model proteins were compared to the separation of a real feedstock. A good agreement was achieved between the developed evaluation procedure and the separation behaviour of the real feed stock.

Abstract
NMR (nuclear magnetic resonance) techniques have been used to measure and characterise solvent flow through chromatographic columns. NMR imaging was used to track an injection of D2O. PGSE (pulsed gradient spin echo) NMR was used to measure the flow-rate dependence of axial and transverse apparent diffusion. A combination of these two techniques (dynamic NMR imaging) gave the spatial distribution of the local velocity and apparent diffusion through a cross-section of the column. Significant column wall effects were observed and these effects were found to be highly dependent upon the column packing density. The column performance was assessed in terms of the HETP (height equivalent to a theoretical plate) determined by the NMR techniques employed.
