Characterization of hemodialysis membranes by inverse size exclusion chromatography [PDF]

, 1995
Inverse size exclusion chromatography (i-SEC) was used to characterize three different cellulosic hollow fiber hemodialysis membranes, i.e. low-flux cuprophan and hemophan and high-flux RC-HP400A.

Liposome retention in size exclusion chromatography

BMC Biotechnology, 2005
Background Size exclusion chromatography is the method of choice for separating free from liposome-encapsulated molecules. However, if the column is not presaturated with lipids this type of chromatography causes a significant loss of lipid material.

Size-exclusion chromatographic NMR of polymer mixtures [PDF]

, 2014
The use of chromatographic stationary phases or solvent modifiers to modulate diffusion properties in NMR experiments is now well established. Their use can be to improve resolution in the diffusion domain or to provide an insight into analyte–modifier ...

Calibration of ultrafiltration membranes against size exclusion chromatography columns [PDF]

, 2010
Using the extension of the concept of universal calibration parameter, yielding a relation between the hydrodynamic volume of molecules and the elution volume in sizeexclusionchromatography (SEC), to retention coefficients in ultrafiltration (UF), we ...

Size exclusion chromatography for extraction of serum bile acids.

Journal of Lipid Research, 1990
A major problem in the measurement of serum bile acids is their quantitative extraction from the high molecular protein matrix. In our hands, the standard techniques of adsorption and reversed-phase chromatography have yielded incomplete recovery for ...

Size exclusion chromatography as green support for forced degradation study of adalimumab

Acta Pharmaceutica, 2023
Size exclusion chromatography (SEC) has become a powerful tool for analysing size variants of biologic drugs in their native form. Modern SEC can be defined by the use of chromatographic columns packed with sub-3 µm particles, allowing an increase in ...

Uncertainty of Size-Exclusion Chromatography Method in Quality Control of Bevacizumab Batches

Separations, 2021
In addition to the analytical challenges related to the size and complexity of biopharmaceutical drugs, the inherent variability that arises due to their manufacturing process requires monitoring throughout the production process to ensure the safety and

Direct iminization of PEEK [PDF]

, 2011
Semi-crystalline poly(ether ketone)s are important high-temperature engineering thermoplastics, but are difficult to characterize at the molecular level because of their insolubility in conventional organic solvents.
