YMC Pack PVA Sil chromatography column (polyvinyl alcohol silica gel column)

YMC-Pack PVA-SilUsing small polymer molecules bonded to the surface of vinyl alcohol, the polymerized vinyl alcohol completely covers the inside and outside of the silicone gel, which can resistpHup to12Buffer solution and solvent.PVA-SilHaving polar vinyl alcohol absorbing groups, it has excellent selectivity for silica gel or other polar bonded phases used in normal phase chromatography. In many cases, it plays a unique role in selection and can dissolve compounds that have weak effects on silica gel. Compounds such as organic bases separated by hydroxyl functional groups on polyvinyl alcohol are more suitable than unbound acidic silica gel.
