More About this Item

These hydrophilic chromatographic columns have diol groups bonded to a silica matrix to separate polar to highly polar compounds that have poor retention on reversed-phase columns. Obtain good retention with eluents containing high concentrations of organic solvents. It has a good separation effect on polar compounds, and it is also used for separation of peptides, proteins, and polar drug molecules.

Columns come in 316L stainless steel (SS) tubing hardware. A SS female end fitting with a SS and PEEK frit system keeps the stationary phase in place and packed bed from disturbance. The SS end fitting accepts a male 10-32 threaded nut with standard 1/16" OD tubing.

Use the guard cartridges to maintain chromatographic integrity. They ensure erroneous materials are kept out of the more important and expensive analytical columns, leading to more accurate results. Simply match the sizes to select the correct guard cartridge for your column; guard cartridge holder 16470-89 is required to use the guard cartridges. In-line filters are available for your UPHLC and HPLC columns—order separately.
