Manufactured to meet research and production requirements, the Hplc Guard Columns (Analytical) Nucleoshell ® Phenyl-Hexyl provide essential protection for your main HPLC column from contaminants. With a length of 4mm and an inner diameter of 2mm, these short columns are designed to be installed between the injector and the HPLC column, preventing chemical impurities from reaching the main column. Featuring reversed phase separation principles, these guard columns are ideal for applications where acetonitrile-water eluents are used. The core-shell, superficially porous particles (SPP) offer a specific surface area of 130 m²/g, ensuring efficient filtration while maintaining temperature stability up to 60°C. The phenylhexyl modification provides pH stability ranging from 1.0 to 10.0, making them
