Micro/Capillary: YMC-Pack PVA-Sil

Normal-Phase Alternative to Silica

YMC-Pack PVA-Sil, which possesses a polyvinyl alcohol (PVA) surface chemistry, is an excellent alternative to silica gel or other polar bonded phases which are used in normal-phase chromatography.  In many situations, it exhibits better performance characteristics with a unique selectivity, and can often resolve compounds that behave poorly on bare silica.  The alcohol functionality present on PVA-Sil is better suited for troublesome compounds, such as organic bases, that acidic silanols present in unbonded silica.  Since PVA-Sil is a bonded stationary phase, it can be washed with solvents of any polarity from hexane to water, without altering the surface activity.  Therefore; selectivity, retention, and resolution are reproducible regardless of the column’s previous history.  This is not true of bare silica, which easily becomes completely deactivated following the introduction of even a small quantity of water.

Polyvinyl Alcohol Functionalized Silica

YMC-Pack PVA-Sil is prepared from a 5µm, 120Å silica support which is bonded with a monomolecular polymer coating of vinyl alcohol. The polymerized PVA completely covers both external and internal surfaces of the silica support, protecting it against aggressive, high pH buffers, and solvents.

  • Bonded phase alternative to silica for normal-phase applications
  • Vinyl alcohol polymerized silica support
  • Consistent surface activity, unaffected by water
  • Excellent for packed column supercritical fluid chromatography
