Pinnacle DB C8 140Å Series

Pinnacle® DB Columns - 1.9µm, 3µm or 5μm particle sizes with 140Å pore size.

Highly base-deactivated spherical silica manufactured by Restek.Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for reducing analysis time, if resolution is adequate.
