SPE polypropylene columns ROTI ® X Bond PRS, 3 ml, 200 mg, 50 unit(s)

Configured for stable performance in synthesis settings, these Spe Polypropylene Columns Roti ® X Bond Prs are ideal additions to any ion exchanger collection for solid phase extraction (SPE). Featuring a silica gel with propylsulfonic acid (PSA) modification, they function as very strong cation exchangers (SCX), offering high recovery rates for pyridinic compounds. Their simple retention mechanism ensures no nonpolar interactions, making them an excellent choice for weak cations such as drugs and their metabolites, basic pollutants like malachite green, gentian violet, tetrodotoxin, and methylene blue. With a specific surface area of 310 m²/g according to BET, these columns offer ample space for efficient separations.
