Optimized for controlled laboratory processes, pre-column systems like the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Ec, 5 µm, 300 Å, 4 x 3 mm, play a crucial role in maintaining the integrity of your main HPLC column. Featuring medium density monomeric octadecyl (C 18, ODS) modification as its surface chemistry, these guard columns provide efficient separation through reversed phase (RP) mechanism. With a specific surface area of 100 m²/g, they offer ample adsorption sites while ensuring pressure stability up to 450 bar. Their pore size of 300 Å allows for optimal elution of analytes using acetonitrile-water mixtures within a wide pH range of 1.0-9.0. By employing these guard
