PVA-Sil, polyvinyl alcohol (PVA) surface chemistry, is an alternative to silica gel or other polar bonded phases which are used in normal phase chromatography.

• Resolve compounds that behave poorly on silica
• Alcohol functionality present on PVA-Sil is better suited for troublesome compounds

Characteristics and a unique selectivity often resolve compounds that behave poorly on silica. The alcohol functionality present on PVA-Sil is better suited for troublesome compounds, such organic bases, than acidic silanols present in unbonded silica.
