YMC America’s J Preston and Jeff Kakaley discuss the 5-in-1 functionality of YMC’s flagship chromatography system – the Contichrom® CUBE. They’ll explore using the instrument for different modes of chromatography, the added benefits of YMC resins, and how the CUBE can be used to scale up to YMC’s TWIN MCSGP systems.

Smaller particle size stationary phases have seen increased use in the modern analytical laboratory due to their ability to exhibit greater resolution while enabling the use of smaller column geometries. Shorter column lengths and narrower bores allow for faster run times and lower flow rates, decreasing laboratory costs in terms of solvent consumption and man-hours needed to run the analyses. This application note examines the effects of smaller particle sizes in various column geometries on size-exclusion chromatography (SEC) methods and the method variables affecting the characterization of antibody products.

The majority of the samples in this study and other studies show that a majority of compounds can be separated by the use of the three most common alcohols: IPA, CH3OH, and ethanol. Solubility becomes a crucial factor in preparative chromatography. Combinations of solvents can be used to improve solubility when the chosen co-solvent has poor solubility of the compound in question.
