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
