SPE polypropylene columns ROTI ® X Bond MAX, 6 ml, 200 mg, 30 unit(s)

Structured to assist in consistent experimental procedures, the Spe Polypropylene Columns Roti ® X Bond Max come packaged as six sets of five units each, providing a total of 30 columns. These open tubular syringe-shaped columns with Luer tip outlets feature a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with quaternary ammonium modification, making them a very strong mixed mode anion exchanger (MAX). With a specific surface area of 300 m²/g according to BET, these columns offer excellent separation capabilities for acidic analytes (pKa 2-8), particularly useful for the enrichment of acidic active ingredients from strongly matrix-contaminated samples such as urine, plasma, or serum. The recommended storage temperature is RT, ensuring their long-term viability and performance
