Prepared for use in regulated laboratory conditions, Spe Polypropylene Columns Roti ® X Bond PSA (Diamino - Quechers) belong to the category of ion exchangers for the SPE. These open tubular syringe-shaped columns with Luer tip outlets come packed with 100 mg of ethylenediamine-n-propyl modified silica gel (PSA), a weak anion exchanger (WAX). This alkylated amine sorbent, featuring both primary and secondary amino groups, offers high ion exchange capabilities due to its pKa values of 10.1 and 10.9, respectively. With a specific surface area of 500 m²/g according to BET, these columns are ideal for the separation and purification of various analytes such as sedatives, fatty acids, organic acids, pigments
