Ion chromatography (IC)—a form of liquid chromatography (LC)—separates and detects ionic compounds in various samples. This technology is appropriate for a wide range of analytes, including anions and cations, amino acids and peptides, carbohydrates and fatty acids, oligonucleotides and polyphosphates, and more. The results provide the concentrations of the various ions in a sample. A wide range of processes in many industries—including electronics, environmental sciences, food and beverage, pharmaceuticals and
This Essential Knowledge Briefing aims to provide a simple introduction to IC, detailing some of the specific implementations, discussing problems that can arise and exploring the developments that are likely to be seen with this technique in the future.
