Polyvinyl Alcohol (PVA) Coated Capillaries, Agilent Technologies
Electrophoresis Systems Capillary Electrophoresis Systems
PVA coated capillaries contain a permanently adsorbed layer of polyvinyl alcohol.

  • Minimizes hydrophobic and electrostatic solute/wall interactions
  • Eliminates electroosmotic flow (EOF)
  • Capillary types available in greater lengths for use in non-Agilent systems
  • PVA is also available for use with the High-Sensitivity Detection Cell
  • PVA-coated capillaries are also offered for CE/MS applications

Agilent provides a broad range of stable polyvinyl alcohol (PVA)-coated capillaries over a wide pH range, from pH 2.5 to 9.5, allowing the use of a wide range of common CE buffers. The capillaries are provided with normally positioned detection window to allow tandem UV-Vis and MS detection for improved sample identification

PVA-coated capillaries contain a permanently adsorbed layer of polyvinyl alcohol. This coating minimizes hydrophobic and electrostatic solute/wall interactions and eliminates electroosmotic flow (EOF). Many proteins and amines can be analyzed without the peak tailing found with uncoated capillaries. In addition, since EOF is eliminated, cumbersome washing procedures are unnecessary and migration time reproducibility can be improved.
