Developed for demanding processing applications, Spe Polypropylene Columns Roti ® X Bond Nh 2 fall under the category of normal phases for the SPE. These columns feature aminopropyl modified silica gel, making them suitable for extraction of moderately polar and acidic compounds. They exhibit hydrogen bonding and weak anion exchange functions, retaining polar compounds like carbohydrates, dyes, lipids, and mycotoxins. Additionally, they serve as a weak anion exchanger for strong anions, such as sulfonic acids, from aqueous solutions, and act as a scavenger for strong acids, chlorides, isocyanates, and electrophiles. Furthermore, these columns also function as metal scavengers for various metals including Pd, Ru, Rh, Cu, Fe, Co, and Ni. With a specific surface area of
