Developed to align with modern chemical standards, the pre-column systems for HPLC, such as the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Ec, 5 µm, 110 Å, 4 x 3 mm, serve as essential components in liquid chromatography (LC, HPLC). These guard columns, specifically designed with medium density monomeric octadecyl (C 18, ODS) modification, protect the main HPLC column from contaminants by acting as a filter. With a particle size of 5 µm and a pore size of 110 Å, they offer a specific surface area of 340 m²/g, ensuring efficient filtration while maintaining pressure stability up to 600 bar. Additionally, their temperature stability extends up to 60°C, making them suitable
