Chromatography

Chromatography is the laboratory technique that separates a mixture into its components by passing it through a medium that holds each compound back by a different amount, and the equipment that performs it covers the pumps, columns, detectors and sample handling that make that separation measurable. On the Questpair catalogue this category runs to 3757 listings from 22 verified suppliers and distributors across 20 countries. Both new and used instruments are listed, and 96 percent of the listings are used, which shapes the prices far more than any single specification does. High-performance liquid chromatography dominates the mix, from standalone modules to complete systems.
