Inerstil ODS-4 3um Guard Column 4.6 x 50mm - 5020-03252

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 example at right, Inertsil ODS-4 is compared with competitive ODS 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 ODS-4 delivers symmetric peaks with high efficiency. 

- Virtually perfect peak shape for most bases and acids - Unmatched base deactivation.
- Predictable selectivity with very low operating pressure making this ideal for fast/LC,  UPLC^TM, and LC/MS
- Exceptional physical and chemical durability provides long column life
- Best choice for polar compounds - bases, acids, etc.
- Compatible with completely aqueous or neat organic eluents
- Low operating back pressure
