| description | A chromatographic separation column for characterizing the purity of a surfactant is disclosed. The column includes a separation medium having a particulate porous matrix retained within the column, the particulate porous matrix having a monofunctional silane, the monofunctional silane having a diisopropyl pendant chain group and a pendant cyano functional group. The porous matrix has a pore size of about # imgabs 0 # to about # imgabs 1 # and an average particle size of about 1.0 [mu] m to about 100 [mu] m. The post has an inner diameter of about 1.0 mm to 100 mm (e.g., 4.6 mm) and a length of about 10 mm to about 250 mm. Methods of facilitating characterization of polysorbate 80 by providing a sample containing polysorbate 80 and one or more reaction products of polysorbate 80 and a chromatographic separation column are disclosed. Also disclosed are methods of characterizing polysorbate 80 by separating polysorbate 80 and one or more reaction products of polysorbate 80.
