Representative Performance from the First Injection

ACQUITY Premier Glycan BEH Amide Columns with MaxPeak High Performance Surfaces (HPS) Technology, that reduces sample loss caused by non-specific adsorption on metal surfaces, deliver the representative performance of Glycan BEH Amide chemistry from the first injection.

• No conditioning or passivation
• Save time and reagents
• Reduce variability of retention time and peak response
• Improve recovery of the phosphorylated glycans  

Released N-Glycan Columns

Waters ACQUITY UPLC and XBridge Glycan BEH Amide 130 Å Columns are best suited for the analysis of released, N-labeled glycans using pre-column labeling with 2-AB, 2-AA, or Waters innovative and enabling RapiFluor-MS reagent. Each batch our Glycan BEH Amide 130 Å chemistry is specifically QC tested with a complex mixture of 2-AB labeled glycans from a mAb digest to help ensure consistent column performance in validated methods.

The image to the right shows the N-linked glycans from pooled human IgG contain high mannose as well as neutral, and sialylated complex structures. The chromatogram shows 35 minutes of a one hour analysis. This challenging sample includes high mannose, bisecting GlcNAc and sialylated species.
