SPE polypropylene columns ROTI ® X Bond PSA (Diamino - QuEChERS), 6 ml, 1000 mg, 30 unit(s)

Built to deliver predictable results in synthesis routines, these Spe Polypropylene Columns Roti ® X Bond PSA (Diamino - Quechers) come housed in a 6 x 5 unit package, each containing a 6 ml column filled with 1000 mg of ethylenediamine-n-propyl modified silica gel (PSA). This weak anion exchanger (WAX) is similar to ROTI ® X Bond NH2, offering excellent performance for the extraction of strong acids and polyacidic compounds from aqueous samples. Its alkylated amine structure, featuring both primary and secondary amino groups, provides enhanced ion exchange capabilities and strong hydrogen bonding, making it ideal for polar compounds. These columns are compatible with various applications such as QuEChERS enrichment, purification, sedatives, fatty
