CHROMABOND® C8

Octyl modified silica phase for SPE, not endcapped

Base material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8. Octyl phase, not endcapped, carbon content 8%, similar to C₁₈, however slightly more polar. Secondary interactions with polar compounds are more pronounced due to shorter alkyl chains.

Recommended applications: pesticides, PCBs.
