Tailored for precision-driven chemical tasks, Spe Polypropylene Columns Roti ® X Bond Sioh offer an unparalleled solution for separating polar compounds within a nonpolar matrix. These open tubular syringe-shaped columns with Luer tip outlets feature fully porous particles (FPP), ensuring optimal performance in normal phase (NP) applications. With a specific surface area of 480 m²/g, these columns provide ample adsorption sites for polar compounds like alcohols, aldehydes, amines, and more. Despite their extreme polarity, they must be stored at room temperature and kept well sealed to prevent absorption of air humidity. For best results, apply analytes in a non-polar solvent before gradually increasing solvent polarity through the addition of polar modifiers such as ethyl acetate or tetrahydrofuran (THF).
