HPLC Guard Columns (analytical) NUCLEODUR ® PolarTec, 1.8 µm, 4 x 3 mm

Tailored for precision-driven chemical tasks, the Hplc Guard Columns (Analytical) Nucleodur ® Polartec, 1.8 μm, 4 x 3 mm, offer robust protection for your main HPLC column from contamination. With a particle size of 1.8 μm and a pore size of 110 Å, these fully porous particles (FPP) provide a specific surface area of 340 m²/g, ensuring efficient filtration. The reversed phase (RP) separation principle, combined with an octadecyl phase (C18, ODS) modification featuring an embedded polar group (PEG), ensures optimal performance under acetonitrile-water eluents. Furthermore, these guard columns boast a pressure stability of up to 800 bar, making them suitable for high-pressure applications. To maintain peak performance
