Retention:
C8 columns offer less retention for hydrophobic compounds than C18 columns due to their shorter alkyl chains. This can be advantageous when analyzing samples that elute too late on C18 columns.

Hydrophobicity:
The octyl chain provides a less hydrophobic environment, making C8 columns suitable for separating moderately hydrophobic compounds.

Pore Size:
The 120 Angstrom pore size indicates the size of the pores within the silica particles, influencing the surface area available for interaction with analytes.

Applications:
C8 columns are widely used in reversed-phase chromatography for various applications, including the separation of pharmaceuticals, environmental samples, and natural products.
