NUCLEOSIL C18 EC

by MACHEREY-NAGEL

 

NUCLEOSIL® standard silica phases for HPLC

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 applications
  • 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

Features:

  • Nonpolar, endcapped phases for RP chromatography
  • Available pore sizes 50, 100, 120, 300, 500, 1000 and 4000 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 (see table below)
  • Separation mechanism based on hydrophobic (van der Waals) interactions, slight residual silanol interactions 
Application areas:
Environmental samples Pharmaceutical molecules
