Abstract
Ion chromatography is an instrumental technique known for its ability to determine and quantify mixtures of ions in solution. In ion chromatography, a solution containing different ions is passed through a column packed with a stationary phase containing active groups (chemical compounds that exhibit binding properties). These active groups show affinity for the various ions in solution. Chemical separations are achieved in ion chromatography by means of electrostatic interactions and coordinate covalent bond formation between the active groups in the stationary phase of the chromatography column and the ions present in the mobile phase or eluent. Strong interactions effectively slow down the rate at which the ions make their way through the labyrinthine packing material. Ions which are not attracted to the stationary phase elute faster and ions which interact with the active groups in the packing material elute slower. The elution of the ions can be identified by a conductivity detector which also helps us to quantify ion concentrations in solution.
