Ion chromatography

Ion chromatography is a liquid chromatography technique that separates ions and polar molecules based on their affinity for a charged stationary phase, with detection most often by suppressed conductivity. A complete setup pairs a pump, a separation column and a detector, and the Questpair catalogue holds 114 such listings from 12 verified suppliers and distributors across 6 countries. Of those, 98 percent of the listings are used. New, used and refurbished laboratory units appear here, with prices from EUR 86 to EUR 137.475. The method quantifies anions such as chloride, nitrate and sulphate, cations, and organic acids at trace levels, which is why it remains a fixture in water, environmental and pharmaceutical laboratories.
