Anion Exchange HPLC Columns: Stability and Reproducibility (PRP-X100)

Ion Chromatography (IC) is a very sensitive technique which requires high quality columns since even very small changes of the packing-material will have a huge impact on the obtained results. In addition, a robust stationary phase is required which delivers proper separations even after a huge number of injections. The reproducibility of Hamilton PRP-X100 anion exchange columns was tested for multiple injections on the same column and for columns from the same as well as from different lots. It was found that the reproducibility was excellent in all cases.
