NUCLEOSIL C6H5

by MACHEREY-NAGEL

NUCLEOSIL® standard silica phases for HPLC


Features

  • 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® C6H5
Phenyl modified silica phases for HPLC
not endcapped · 8 % C · USP L11


Features

  • Relatively nonpolar phases for RP and ion pairing chromatography
  • Available pore sizes 100, 120, 300, 500 and 1000 Å, available particle sizes 5 µm and 7 µm,                                                                      pH stability at 20 °C: 2–8; carbon content 8 %
  • Polarity similar to C8, but with different selectivity for polycyclic aromatic hydrocarbons, polar aromatics, fatty acids etc.
  • Separation mechanism based on π–π interactions and hydrophobic (van der Waals) interactions, some residual silanol interactions
Application areas:
Aromatic compounds
