Shodex Product Number: F6711200

The robust Polymer-based Amino HILIC column for many general applications

Specifications:

VG-50 2D allows simultaneous analysis of saccharides, organic acids and amino acids with LC/MS detection under alkaline conditions. High anionic substances elute under alkaline conditions. Furthermore, alkaline conditions promote the deprotonation of hydroxyl groups at the time of ionization. Therefore, alkaline conditions are suitable for high sensitive detection of substances with hydroxyl groups such as saccharides under the negative mode.

• Suitable for saccharide analysis using HILIC mode
• Recovers reducing saccharides with high ratio (usage of tert. amine groups to avoid building of Schiff base)
• Polymer-based packing material provides excellent chemical stability and minimum deterioration
• over an extended time period
• pH stability: 2 to 13 (silanol free)
• Easily regenerated by washing in an alkaline solution
• Also suitable for evaporative light scattering detector (ELSD), corona charged aerosol detector (CAD), and mass spectrometry (LC-MS/MS)
• Adsorption of acidic substances on the amino functional group.
  - Flush with solvents in the following sequence; water, 0.1 M NaOH (aq.), water, and the
  eluent.
• Suitable for: Amino acids - HILIC | Organic acids - HILIC | Mono-, di-saccharides,
  and sugar alcohols Saccharides and sugar alcohols - HILIC | Amino sugars - HILIC | Water-soluble vitamins - HILIC
