Princeton Chromatography, Inc., New Jersey manufactures both HPLC and SFC columns.

SFC Overview

Supercritical Fluid Chromatography (SFC) applications typically require polar stationary phases such as silica, amino and diol. Although these phases are adequate for many applications, there is still a need for additional polar phases to meet the demands of difficult separations.


Princeton Chromatography has developed a series of amide, urea and pyridine phases that enhance the capability of the SFC technique. Princeton Chromatography was the first company to develop and market the 2-Ethylpyridine phase which was launched in 2001. PrincetonSFC 2-Ethylpyridine is the column of choice for achiral SFC analysis of basic compounds. This phase requires no addition of amines to the eluent, producing excellent peak shape and reproducibility.PrincetonSFC analytical columns are available with lengths of 50 to 250mm and i.d.s of 2.0, 3.0, 4.0 or 4.6mm. PrincetonSFC semi-preparative and preparative columns are available in i.d.s up to 50mm and larger. All PrincetonSFC columns are individually quality assured by SFC.
