Crafted to support technical production environments, the Spe Polypropylene Columns Roti ® X Bond Sax come in a packing of 4 x 5 units, each containing 12 ml of 2000 mg filling. These open tubular syringe-shaped columns with Luer tip outlets are made of PP columns with PE filter elements, featuring a pore size of 70 Å and particle size ranging from 40-75 µm. The strongly basic anion exchanger (SAX), crafted from silica gel with quaternary ammonium modification, offers a specific surface area of 510 m²/g and a recommended storage temperature of RT. This phase is ideal for separating caffeine, organic acids, and saccharin through ion exchange (IEX). It's essential to note that while it retains weaker anions like carboxylic acids
