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

Developed to align with modern chemical standards, Spe Polypropylene Columns Roti ® X Bond Max are ion exchangers specifically designed for Solid Phase Extraction (SPE), falling under the category of chromatography labware. These columns feature a unique combination of reversed phase and strong anion exchange retention mechanisms, making them ideal for the enrichment of acidic analytes with pK values ranging between 2 and 8. Constructed as open tubular syringe-shaped columns with Luer tip outlets, they boast a specific surface area of 300 m²/g, as per the BET method, and come filled with 200 mg of hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with quaternary ammonium modification, creating a very strong mixed mode anion exchanger known as MAX
