Prepared for use in regulated laboratory conditions, Spe Polypropylene Columns Roti ® X Bond PSA (Diamino - Quechers) are ideal for the extraction of strong acids and polyacidic compounds from aqueous samples. These open tubular syringe-shaped columns with Luer tip outlets, filled with 200mg of ethylenediamine-n-propyl modified silica gel, function as weak anion exchangers (WAX) due to their primary and secondary amino groups. This makes them suitable not only for the separation of polar analytes from non-aqueous matrices but also for the complexation with certain metal cations. With a specific surface area of 500 m²/g and a carbon content of 8%, these columns offer high ion exchange capabilities and strong hydrogen bonds, making them a preferred choice for polar compounds.
