Ion chromatography (IC) is an analytical technique for the separation and determination of ionic solutes in water in general especially environmental in industrial processes, metal industry and industrial waste water in biological systems in pharmaceutical samples in food etc. IC can be classified as a liquid chromatographic method, in which a liquid permeates through a porous solid stationary phase and elutes the solutes into a flow-through detector. The stationary phase is usually in the form of small-diameter (5-10 mm) uniform particles, packed into a cylindrical column. The column is constructed from a rigid material (such as stainless steel or plastic) and is generally 5-30 cm long and the internal diameter is in the range of 4-9 mm. A high pressure pump is required to force the mobile phase through the column at typical flow rates of 1-2 ml/min. The sample to be separated is introduced into the mobile phase by injection device, manual or automatic, prior to the column. The detector usually contains low volume cell through which the mobile phase passes carrying the sample components.
