Prepared for use in regulated laboratory conditions, the Spe Polypropylene Columns Roti ® X Bond PSA (Diamino - Quechers) arrive packaged in sets of 10 x 5 units. These open tubular syringe-shaped columns with Luer tip outlets feature a weak anion exchanger (WAX) phase made from silica gel with ethylenediamine-n-propyl modification. Each column holds 3 ml of this material, which is filled with 200 mg of fully porous particles (FPP) sized between 50-75 µm. This PSA (Diamino - QuEChERS) phase exhibits a specific surface area of 500 m²/g according to BET, and its particle type ensures optimal performance for the separation of polar compounds via ion exchange (IEX). The recommended applications include Qu
