Ion pair chromatography
Ion-Pair Reagents for HPLC and Ion-Pair Chromatography
Ion-pair reagents are used in high-performance liquid chromatography (HPLC) to improve the separation of polar and ionic compounds in particular. They act as counterions or mobile phase modifiers and can selectively influence selectivity and retention in chromatographic separations.
Our range includes high-purity alkanesulfonates for HPLC, including the sodium salts of butane-, pentane-, hexane-, heptane- and octanesulfonic acid. They are suitable for demanding applications in analysis, research and quality control where reliable and reproducible chromatographic results are required.
