Prepared for use in regulated laboratory conditions, the Spe Polypropylene Columns Roti ® X Bond Nh 2 serve as normal phases for Solid Phase Extraction (SPE). These columns feature aminopropyl modified silica gel, functioning as a polar weak anion exchanger suitable for extracting moderately polar and acidic compounds. With hydrogen bonding and weak anion exchange capabilities (pKa <9.8), they retain polar compounds like carbohydrates, dyes, lipids, and mycotoxins. Additionally, they can act as a weak anion exchanger to retain strong anions, such as sulfonic acids, from aqueous solutions, and as a scavenger for strong acids, chlorides, isocyanates, and electrophiles. Furthermore, these columns also serve as metal scavengers for various metals including P
