Optimized for controlled laboratory processes, the Spe Polypropylene Columns Roti ® X Bond Nh 2 come in a packing of 4 x 5 units, each containing 2000mg of aminopropyl modified silica gel. This polar weak anion exchanger is ideal for extracting moderately polar and acidic compounds due to its hydrogen bonding and weak anion exchange function, with a pKa less than 9.8. It retains polar compounds, carbohydrates, dyes, lipids, and mycotoxins, making it also useful as a weak anion exchanger for strong anions like sulfonic acids. Additionally, it serves as a metal scavenger for various metals including Pd, Ru, Rh, Cu, Fe, Co, and Ni. These columns are compatible with a wide pH range of 2.
