HPLC Guard Columns (analytical) NUCLEODUR ® C 18 Isis, 3 µm, 4 x 2 mm

Adapted for use across diverse chemical handling environments, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Isis offer enhanced protection for your primary HPLC column against contaminants. With a particle size of 3 μm and a column length of 4 mm, these guard columns feature fully porous particles (FPP), nonpolar crosslinked polymeric octadecyl (C 18 , ODS) modification, and high steric selectivity. The columns' pore size of 110 Å, specific surface area of 340 m²/g, and pH stability range of 1-10 ensure compatibility with various eluents, including acetonitrile-water mixtures. The pressure stability of up to 600 bar allows for efficient operation within a wide range of conditions. By using these guard columns, you can extend
