Inertsil
Inertsil columns were developed by GL Sciences in 1986 for sample separations using high-performance liquid chromatography. Starting with Inertsil ODS, a new type of bonded silica was produced providing unmatched performance and reproducibility. Further refinements of evolved silica and the introduction of new phases have allowed Inertsil to achieve industry leading performance for analyte separation to become one of the most highly used columns for HPLC.
