HPLC columns

HPLC columns are the separation core of a high-performance liquid chromatography system, packed tubes through which a pressurised mobile phase carries a sample so that its components elute at different times. The column holds the stationary phase, usually silica particles bonded with a specific chemistry, and that chemistry decides what separates and how well. On Questpair the catalogue runs to 207 listings from 11 verified suppliers and distributors across 10 countries. New, used and refurbished columns are listed, and 91 percent of the listings are used. Prices run from EUR 9 to EUR 12.913. A laboratory sourcing a replacement or a second-hand instrument column works from the same figures.
