Amino

Amino HPLC columns carry an amine-bonded silica used for normal-phase and HILIC-type separations of sugars and other polar analytes. Food, pharmaceutical and academic laboratories use them where reversed-phase C18 columns give little retention.

With 282 listings, this is one of the larger sections of the HPLC Columns catalogue. It is built around the Vintage Chrom Bond Amine HD family, including 125 × 4 mm analytical columns with 3 µm and 5 µm particles and a choice of 60 Å, 100 Å and 200 Å pore sizes.

Smaller pores suit small molecules; the 200 Å option gives larger analytes better access to the bonded phase. If you are moving a method between amino columns, the particle size and pore size of your current column are the first things to match. Ask for a quotation on any Bond Amine HD column.
