SPE polypropylene columns ROTI ® X Bond WAX, 3 ml, 500 mg, 50 unit(s)

Developed to align with modern chemical standards, these Spe Polypropylene Columns Roti ® X Bond Wax are part of the ion exchangers for the SPE category. They boast a unique combination of materials - PP columns with PE filter elements - that make them ideal for use in the lab. With a specific surface area of 600 m²/g according to BET, these columns offer excellent separation capabilities. Featuring a mixed mode separation principle (RP and Ion exchange (IEX)), they excel at the enrichment of strongly acidic analytes (pKa <1), making them particularly suitable for determining strong acidic pollutants such as perfluorinated carboxylic acids in environmental and water samples. Their recommended storage temperature is RT, ensuring their long-term effectiveness. For those seeking additional options, similar phases include Oasis ® WAX, Strata™-X-AW,
