Widely applied in chemical workflows, Spe Polypropylene Columns Roti ® X Bond Sax are open tubular syringe-shaped columns filled with quaternary ammonium-modified silica gel, functioning as a strongly basic anion exchanger (SAX). These columns are particularly useful for retaining weaker anions like carboxylic acids, sulphonic acids, and phosphates that might not bind strongly enough on weaker anion exchange phases. With a pH stability range of 2.0-8.0, these columns offer versatile applicability across various chemical processes. They come pre-filled with 200mg of material and have a specific surface area of 510 m²/g according to BET. Their particle size ranges between 40-75 µm, making them suitable for a variety of separation tasks, including the purification of organic ac
