MCI Gel™ Ion Chromatography Columns

The Mitsubishi Chemical Corporation MCI Gel™ ion chromatography columns are based on functionalized cation and anion exchange resins specially designed for non-suppressed ion chromatography applications. Non-suppressed ion chromatography is facilitated by the combination of a column based on low-capacity ion exchange resin and an eluent with low electrolyte concentration.

  • The MCI Gel™ SCK01 cation chromatography column is based on a crosslinked polystyrene resin functionalized with sulfonic acid. The SCK01 columns are available in two sizes: 6 x 50 mm and 4.6 x 150 mm, providing excellent resolution and fast analysis of monovalent and divalent cations. Standard monovalent ions like Li+, Na+, NH4+, K+, Rb+, Cs+ and simple amines such as mono, di, and trimethylamine can be resolved using a nitric acid solution as eluent. Divalent cations, such as alkaline earth metals and transition metal elements, can be efficiently resolved using tartaric acid and a complexing agent such as ethylen diamine to selectively elute the metals from the column. When using the SCK01 column for monovalent ions it is advised to use the SCK-PC pre-column to trap any possible heavy metals in order to avoid losing capacity and chromatographic performance.
  • The MCI Gel™ SCA04 anion chromatography column is based on a hydrophilic 5 µm particle size polyhydroxymethacrylate resin functionalized with quaternary ammonium groups. The SCA04 is a PEEK column (6 x 150 mm). A solution of potassium hydrogen phthalate and a vanilic acid (VA)/N-Methyldiethanolamine (MDEA) can be used as an eluent. The VA/MDEA eluent is specifically developed for the SCA04 column enabling the analysis of 7 standard anions in 14 minutes without any system peak. To extend the column life it is advised to use the SCA-PC pre-column between the eluent pump and the injector.
