Ion chromatography

Ion chromatography is a liquid chromatography technique in which ions are separated on the basis of their affinity to the ion exchange stationary phase in the column. Both positive and negative ions can be analysed with this technique, in addition to inorganic ions, organic compounds such as amino acids, nucleotides, sugars and proteins can also be analysed if in charged state. As the solvents used for elution reach extreme pH, no metal parts can come into contact with the liquid flow to prevent their corrosion.
