50mL of x4 LS-C buffer concentrate (2.0M ammonium formate buffer, pH 9.0). This can be diluted with water and acetonitrile to prepare LS-C solvent (500 mM ammonium formate buffer pH 9, 20% acetonitrile v/v) used in WAX (weak anion exchange) HPLC analysis of LudgerTag fluorophore and UV-chromophore labelled glycans.

LudgerSep™C2 HPLC columns contain particles with a macroporous polymeric anion exchange coating optimized for anion exchange chromatography of complex glycan mixtures. The LudgerSep strong anion exchange column is used for determining the charge profile of 2-AB and 2-AA labelled glycans as part of biopharmaceutical QC procedures.

Analysis and purification by HPLC of LudgerTag™ fluorophore and UV-chromophore labelled glycans. LudgerSep™ N1 HPLC columns contain particles with a polymeric amide coating optimized for high-resolution chromatography of complex glycan mixtures.

50 mL of x10 LS-BPT (butylamine/orthophosphoric acid/tetrahydrofuran) solvent.

Analysis by HPLC of sialic acid variants fluorophore labelled with DMB (1,2-diamino-4,5-methylenedioxybenzene.2HCl) using the LudgerTag DMB Sialic Acid labelling Kit.

Analysis of monosaccharides labelled with 2-aminobenzoic acid (2-AA) using UHPLC.

A strong anion exchange column used for determining the charge profile of 2-AB and 2-AA labelled glycans as part of biopharmaceutical QC.

50ml of x40 LS-N buffer concentrate (2.0M ammonium formate buffer, pH 4.4). This can be diluted with water to prepare LS-N buffer (50 mM ammonium formate buffer, pH 4.4) used in amide or HILIC (hydrophilic interaction liquid chromatography) HPLC analysis of LudgerTag fluorophore and UV-chromophore labelled glycans.

Analysis and purification by HPLC of LudgerTag™ fluorophore and UV-chromophore labelled glycans. LudgerSep™ N1 HPLC columns contain particles with a polymeric amide coating optimized for high-resolution chromatography of complex glycan mixtures.
