Robust polymer-based HILIC column for negatively charged analytes.

• Polymer-based HILIC columns with quaternary ammonium (-NR3+) groups
• Best for glyphosate analysis and phosphorylated sugars
• Suitable for anionic substances (especially phosphate compounds) analysis using HILIC mode
• Use of some eluents add ion exchange mode
• Polymer-based packing material provides excellent chemical stability and minimum deterioration over an extended time period
• Suitable for LC-MS/MS analysis

The HILICpak VT-50 column with quaternary ammonium groups is a robust HILIC column for anionic substance analysis. The polymeric base material polyvinyl alcohol offers great stability from pH 2 - 13. The column housing is made of PEEK to reduce unwanted interaction.
