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® C6H5
Phenyl modified silica phases for HPLC, not endcapped
USP L11
Features
- Relatively nonpolar phases for RP and ion pairing chromatography
- Pore size 100 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.
