Robust polymer-based HILIC column for separation by size/chain length.

• Polymer-based HILIC columns with diol (-OH) groups
• Best for oligosaccharides and oligonucleotides
• Suitable for oligomer separation which is not possible by SEC column or conventional HILIC columns
• The modified diol groups on the packing material create the HILIC mode
• Polymer-based packing material provides excellent chemical stability and minimum deterioration over an extended time period
• pH stability: 2 to 13
• Also suitable for evaporative light scattering detector (ELSD), corona charged aerosol detector (CAD), and mass spectrometry (LC-MS/MS)

The HILICpak VN-50 columns with diol groups are robust HILIC columns for separating analytes by their degree of polymerisation. The polymeric base material polyvinyl alcohol offers great pH stability. The column housing is made of PEEK to reduce unwanted interaction.
