SPE polypropylene columns ROTI ® X Bond PSA (Diamino - QuEChERS), 3 ml, 100 mg, 50 unit(s)

A reliable solution for controlled synthesis, Spe Polypropylene Columns Roti ® X Bond Psa (Diamino - Quechers) offers a versatile option for the extraction of strong acids and polyacidic compounds from aqueous samples. This open tubular syringe-shaped column with Luer tip outlet features fully porous particles (FPP) of 50-75 µm in diameter and a specific surface area of 500 m²/g, ensuring efficient separation. The phase material, ethylenediamine-n-propyl modified silica gel (PSA), functions as a weak anion exchanger (WAX) due to its primary and secondary amino groups with pKa values of 10.1 and 10.9, respectively. With a carbon load of 8%, this PSA provides superior performance for polar compounds
