GreenSep Supercritical Fluid Chromatography (SFC) LC Columns

Many SFC separations have utilized “older normal phase HPLC types” of stationary phases such as unmodified silica, diol, amino and cyano. These phases are poorly adapted to SFC and present a number of limitations for SFC separations including low capacity, poor selectivity and poor peak shape. GreenSep stationary phases, on the other hand, have been specifically engineered for SFC separations, paying close attention to bonding coverage, density and all factors leading to high capacity phases which exhibit excellent selectivity and peak shape.

The GreenSep range features a variety of selectivities offering orthogonality. All of these materials are available in analytical and also semi-preparative (10 mm), and preparative (20 mm, 30 mm and 50 mm i.d.) dimensions. Additionally, comprehensive technical and method development assistance is offered. Shown below is a column selection guide for the development of a SFC separation with the GreenSep Pyridyl Amide being the go-to column of choice, followed by the other columns.
