chiral stationary phases (CSP) - stationary phases that are designed to separate enantiomeric compounds. They can be bonded to solid supports or created in situ on the surface of the solid adsorbent or they can be surface cavities that allow specific interactions with one enantiomeric form.
See chiral phases.
column - (chromatographic column) Usually stainless steel tube with polished inner surface and endfittings at both ends densely packed with small porous adsorbent particles.
See also column hardware.
column chromatography - any form of chromatography that uses a column or tube to hold the stationary phase. Open-column chromatography, HPLC, and open-tubular capillary chromatography are all examples.
conductivity detector - HPLC device for continuous monitoring effluent conductivity. Usually used with ion chromatography.
See electrolitic conductivity detector.
correction factor - syn. response factor; calculation coefficient which corrects the different response of detectors to different compounds; used to convert peak areas to numbers proportional to weight of sample.
counterion - in an ion-exchange process, the ion in solution used to displace the ion of interest from the ionic site. In ion pairing, it is the ion of opposite charge added to the mobile phase to form a neutral ion pair in solution.
