YMC-Pack PVA-Sil
YMC-Pack PVA-Sil Biochromatography Columns
YMC Pack PVA-Sil, which possesses a polyvinyl alcohol (PVA) surface chemistry, is an excellent alternative to silica gel or other polar bonded normal phases. The polymerised PVA completely covers both external and internal surfaces of the silica support, protecting it against aggressive, high pH buffers and solvents.
In many situations it exhibits better performance characteristics and a unique selectivity and can often resolve compounds that behave poorly on silica. The alcohol functionality present on YMC Pack PVA-Sil is better suited for troublesome compounds, such organic bases, than acidic silanols present in nonbonded silica.
