Prepared for use in regulated laboratory conditions, the Hplc Guard Columns (Analytical) Nucleoshell ® PFP, 4 x 2 mm, are designed as pre-columns to protect your main HPLC column from contamination. With a particle size of 2.7 µm and a pore size of 90 Å, these core-shell, superficially porous particles (SPP) offer a specific surface area of 130 m²/g. The columns feature a reversed phase (RP) separation principle and a surface chemistry of pentafluorophenylpropyl (PFP). They are end-capped, have a pressure stability of 600 bar, and are suitable for eluents such as acetonitrile-water. The columns measure 4 mm in length and 2 mm in inner diameter, making them ideal for use in a
