GL Sciences’ Original High Purity ODS PhaseWhen Inertsil ODS-2 was introduced in the late 1980s, this HPLC transformed the entire industry. Inertsil ODS-2 was the first HPLC phase created using ultra high purity silica, which produced superior base deactivation. Additionally, a unique “oligomeric” bonding architecture created a novel selectivity and a degree of chemical and physical ruggedness as yet unseen. Until this phase was eclipsed by the performace of it’s sibling Inertsil ODS-3 (and now, by Inertsil ODS-4), it was GL Sciences’ most popular phase and continues to be used widely and reliably for long established methods in pharmaceutical and environmental labs. While Inertsil ODS-2 is generally recommended primarily for following prescribed methods, (Inertsil ODS-4 and ODS-3 being recommended for new methods) it constitutes of one of six Inertsil ODS phases offering alternative selectivities for polar compounds.

Pure Reverse Phase Chromatography

The absence of metals and other impurities in Inertsil ODS-2 silica, combined with robust end-capping allows pure reverse phase chromatography for even the most polar compounds.

The chromatograms at left show selectivity differences between Inertsil ODS-2 and GL Sciences’ more advanced ODS phases.
