Inertsil ODS-EP

Embedded Polar ODS Phase

Inertsil ODS-EP contains a polar functional group embedded between the silica surface and the C18 group. The embedded polar group makes the C18 phase stable in 100% aqueous eluents without "phase collapse." This phase is also extremely "base deactivated" and provides superior peak shape for acids and bases in organic eluents as well as acidified eluents typically used in LC/MS. Inertsil ODS-EP is available in 5 micron particle size in column configurations ranging from capillary to 50mm ID preparative sizes.
