Inertsil ODS-4
The Most Deactivated Column Ever Made
GL Sciences’ newly-developed chemical bonding technology allows Inertsil ODS-4 to provide high efficiency and good peak shape where competitive columns fail. For example, in the examples at right, Inertsil ODS-4 is compared with competitive ODS phases for the analysis of basic and acidic compounds. Where other columns show poor peak shape, often with secondary interactions that result in prolonged retention, Inertsil ODS-4 delivers symmetric peaks with high efficiency.
Inertsil ODS-4 (and C8-4) is also available in 2 micron particle sizes for UHPLC.
