Ion Chromatography

Ion chromatography (or ion-exchange chromatography) is a chromatography technique that separates ions and polar molecules based on their affinity to the ion exchanger. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range. Ion chromatography is a simple, fast, convenient and efficient method, making it popular in a number of industries such as electronic, clinical, biological, pharmaceutical, chemical and food.
