Produced to ensure dependable processing results, the Hplc Guard Columns (Analytical) Nucleodur ® Polartec, 3 μm, 4 x 3 mm feature a reversed phase separation principle and are designed with fully porous particles (FPP). With a pore size of 110 Å and a pore volume of 0.9 ml/g, these guard columns offer optimal performance when used with acetonitrile-water eluents. Featuring octadecyl phase (C18, ODS) modification with embedded polar groups (PEG), they provide excellent pH stability ranging from 1.0 to 9.0 and pressure stability up to 600 bar. Their specific surface area, as per BET, is 340 m²/g, ensuring efficient adsorption capabilities. To further extend the lifespan of your main HPL
