Tailored for precision-driven chemical tasks, Spe Polypropylene Columns Roti ® X Bond Sioh offer an unmatched 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 during normal phase (NP) separations. With a specific surface area of 480 m²/g according to BET, these columns provide ample adsorption sites for polar compounds such as alcohols, aldehydes, amines, and phenols. Their unique composition—unmodified silica gel (SiOH)—makes them suitable for applications ranging from pharmaceuticals to dyes and herbicides. However, due to their extreme polarity, they must be stored properly at room temperature and should never be conditioned with polar solvents like methanol or water
