HPLC column (analytical), NUCLEOSIL 100-10 C18, length: 250 (C08-0494-364)

NUCLEOSIL® is a family of totally porous spherical silicas with a very pure and uniform SiO2 structure Wide acceptance as routine packings for very different fields of chromatography One of the first spherical silicas used in HPLC Developed in the early seventies, it became a world-renowned HPLC packing Still found in many analytical and preparative application An absolutely reliable choice in HPLC The largest variety of modified HPLC silicas available on the market NUCLEOSIL® standard C18 phases Octadecyl modified silica phases for HPLC, endcapped USP L1 Features Nonpolar, endcapped phases for RP chromatography Available pore sizes 50, 100, 120, 300, 500 and 1000 Å Available particle sizes 3 µm, 5 µm, 7 µm and 10 µm pH stability at 20 °C: 2–8 Carbon content depending on pore size, e.g.,50 Å (14.5 %), 100 Å (15 % C) - 1000 Å ~ 1 % C Separation mechanism based on hydrophobic (van der Waals) interactions, slight residual silanol interactions Corresponding NUCLEODUR® phases: see NUCLEODUR® C18 ec
