Optimized for controlled laboratory processes, the Spe Polypropylene Columns Roti ® X Bond Sax come in packaged sets of 10 x 5 units, each containing 3 ml columns filled with 500 mg of quaternary ammonium-modified silica gel, a strong basic anion exchanger (SAX). These open tubular syringe-shaped columns feature Luer tip outlets and a particle size range of 40-75 µm. With a specific surface area of 510 m²/g according to BET, these columns offer excellent separation capabilities for applications like caffeine and organic acids. Their pH stability ranges from 2.0 to 8.0, making them versatile for various lab environments. Additionally, their surface chemistry retains weaker anions such as carboxylic acids, sulphonic acids, and phosphates,
