Polyvinyl alcohol (PVA) coated capillaries

Leverancier: Agilent
Omschrijving: PVA coated capillaries contain a permanently adsorbed layer of polyvinyl alcohol. This coating minimises hydrophobic and electrostatic solute/wall interactions and eliminates electroosmotic flow (EOF). Using a proprietary deposition process, the PVA coating is stable over a wide pHrange, even under basic conditions from 2,5 to 9,5. This stability allows the use of many common CE buffers. Because the silica surface is covered, many proteins and amines can be analysed without the peak tailing found with uncoated capillaries. In addition, since EOF is eliminated, cumbersome washing procedures are unnecessary and migration time reproducibility may be improved.
