Formulated to support synthetic operations, Spe Polypropylene Columns Roti ® X Bond Sax provide a strong basic anion exchanger (SAX) functionality for separating weak acids, sulfonyl chlorides, isocyanates, biomolecules, and weak electrophiles in your lab. These open tubular syringe-shaped columns feature fully porous particles (FPP), a pore size of 70 Å, and a particle size range of 40-75 µm. With a filling quantity of 100 mg per unit, these columns offer a specific surface area of 510 m²/g according to BET, ensuring efficient separation. The recommended applications include caffeine, organic acids, and saccharin.
