Ion chromatography (IC)

Information obtained

  • Identification of ions in aqueous solutions
  • Determination of concentration, particularly for anions and complex ions

Principle

Ion exchange chromatography (or ion chromatography) is a process that allows the separation of ions and polar molecules, using their charge properties. It can be used for almost any kind of charged species, including large proteins, small nucleotides and amino acids. Our system can be fitted with an anion exchange column, a cation exchange column or an organic acids column. The anion exchange column is especially useful for determining ppm concentrations of common anions such as chloride, phosphate and sulphate in aqueous solutions.

Example:

Tap water - beskåret
Chromatogram of the tap water in our laboratory – the concentration units are ppm.
