GL Sciences’ newly-developed chemical bonding technology allows Inertsil C8-4 to provide high efficiency and good peak shape where competitive columns fail. For example, in the exampleat right, Inertsil C8-4 is compared with competitive Octyl phases for the analysis of dextromethorphan, a basic compound. Where other columns show poor peak shape, often with secondary interactions that result in prolonged retention, Inertsil C8-4 delivers symmetric peaks with high efficiency
