Designed with efficiency in synthetic processes in mind, the Pre-column systems for HPLC category offers solutions like the Hplc Guard Columns (Analytical). Specifically, the Nucleodur ® C 18 Gravity, 1.8 μm, 4 x 3 mm model. These guard columns protect your main HPLC column from contamination by filtering out chemical impurities before they reach the main column. Featuring a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of 800 bar, this guard column ensures optimal performance and longevity for your main column. Its reversed phase (RP) separation principle, combined with its bifunctional RP phase and balanced ratio of propylphenyl and C 18 ligands, makes it suitable for acetonitrile-
