Formulated to support synthetic operations, the pre-column systems for HPLC, such as the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Ec, 3 μm, 110 Å, 4 x 2 mm, play a crucial role in maintaining the integrity of your main HPLC column. With a pore size of 110 Å and a particle size of 3 μm, these guard columns effectively filter out potential contaminants, preventing them from reaching and damaging the main column. Their medium density monomeric octadecyl (C 18, ODS) modification ensures efficient separation principles through reversed phase (RP), while their temperature stability up to 60°C allows for versatile application.
