CHROSPE | Phenyl EC

Sorbent code: Y25
Part number: AS-SP-0621.004, 10 x1 mm ID

Silica-based sorbent with a phenyl phase and end-capping. Non-polar phase, with similar polarity compared to a C8 phase. However, due to the electron density present in the aromatic ring, the phenyl phase shows an enhancement in the retention of planar and conjugated or aromatic ring-containing analytes due to desirable pi-pi interactions. Therefore, there is a different selectivity compared to alkyl phase such as C8 or C18 phases.
