Tailored for precision-driven chemical tasks, Spe Polypropylene Columns Roti ® X Bond Prs offer a robust solution for ion exchange chromatography (IEX), particularly suited for weak cations such as drugs and their metabolites, basic pollutants like malachite green, gentian violet, tetrodotoxin, and methylene blue. These open tubular syringe-shaped columns with Luer tip outlets feature fully porous particles (FPP) of 40-75 μm, ensuring efficient separation due to their specific surface area of 310 m²/g, as per BET. The silica gel matrix is modified with propylsulfonic acid (PSA), making it a very strong cation exchanger (SCX), capable of high recovery rates for pyridinic compounds. Notably, PRS exhibits a unique selectivity,
