Platinum Cyano 100Å - 3µm

Controlled silica exposure is the difference that makes Platinum Columns unique. The approach taken by most column manufacturers in making reversed-phase columns is to thoroughly cover the silica with bonded phase to minimize any interaction between polar analytes and the packing medium’s silica backbone. Platinum media takes a different approach. Instead of maximizing the coverage of bonded phase to hide the silica, the exposure of the silica is controlled to provide a dual mode separation medium with both polar and non-polar sites exposed to your samples. This extends polar selectivity well beyond what other reversed-phase columns offer and gives separations other columns cannot.

Platinum Columns come in two varieties offering different levels of silica exposure. Standard Platinum has a moderate silica exposure and is best used with neutral and moderately polar compounds. Platinum EPS (Extended Polar Selectivity) has a high level of silica exposure and is best used with compounds containing more than two polar functional groups
