|Phenyl modified silica phases for HPLC|
|not endcapped · 8 % C · USP L11|
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
