  • LudgerSep N series columns
  • Tosoh Amide-80 columns
  • Waters ACQUITY UPLC BEH glycan columns
  • GlycoSep N and N-Plus columns
  • Other HILIC HPLC columns for glycan analysis

Includes 50ml of x40 LS-N buffer (2.0M ammonium formate buffer/solution) in a square HDPE bottle with leak-proof cap.

Dilute with de-gassed HPLC grade water (use 1 part of x40 buffer to 39 parts of water) to make LS-N buffer (50 mM ammonium formate, pH 4.4). The 50 ml of x40 buffer will make 2 litres of LS-N buffer.
