Related applications: Industrial ChromatographyPacked with a special chelating resin, the Thermo Scientific™ Dionex™ MFC-1 and MFC 500 Metal-Free Trap Columns are used in the eluent line prior to the injection valve to remove transition metals from high-pH eluents. The Dionex IonPac MFC 500 is identical to the Dionex IonPac MFC-1, but is packed in a column body that is compatible with nonstop operation up to 5,000 psi.
The Dionex IonPac MFC-1 and Dionex IonPac MFC 500 Metal-Free Trap Columns contain resin functionalized with covalently bonded iminodiacetic acid functional groups. These metal-free trap columns strip transition and lanthanide impurities which are too concentrated for trace analysis from the eluent. The metals that are trapped by the Dionex IonPac MFC-1 and Dionex IonPac MFC 500 can be easily removed form the trap columns with acidic regenerants.
