Inertsil ODS-EP Analytical Columns, Particle Size 5µm, I.D. 4.0mm, Length 150mm, GL Sciences Inc. (CAT#: STEM-C-3432-LC)

Inertsil ODS-EP Analytical Column manufactured by GL Sciences Inc. features a polar functional group which is embedded between the silica surface and the C18 group, making C18 phase stable in 100 % aqueous eluents without "phase collapse." This phase is also ultra "base deactivated" and offers superior peak shape for acids and bases in organic eluents as well as acidified eluents typically used in LC/MS.
