Engineered to maintain reliability in process-driven workflows, pre-column systems for HPLC, such as the Hplc Guard Columns (Analytical) Nucleodur ® C 4 Ec, 4 x 2 mm, play a crucial role in protecting your main HPLC column from contamination. Featuring a medium density monomeric butyl (C 4 ) wide-pore modification, these guard columns offer a specific surface area of 100 m²/g, ensuring optimal separation performance. With a particle size of 5 µm and a pore size of 300 Å, they provide a high pore volume of 0.9 ml/g and a pressure stability of up to 450 bar. Designed for compatibility with acetonitrile-water eluents, these guard columns exhibit excellent temperature stability up to 60°C and
