• This is a reversed-phase column with an octadecylsilyl (ODS) stationary phase that is highly base deactivated. This deactivation allows for the chromatography of strong bases without the need for buffers in the eluent.
• ODS-B: This signifies an ODS (C18) column with enhanced base deactivation. This means the silica surface, which typically contains silanol groups (Si-OH) that can interact with basic compounds, has been modified to minimize these interactions.
• Reversed-Phase Chromatography: ODS columns are commonly used in reversed-phase chromatography, where the stationary phase (ODS) is non-polar and the mobile phase is typically a mixture of water and an organic solvent (like acetonitrile or methanol).
• Base Deactivation: The primary advantage is the ability to separate basic compounds without the need for buffers in the mobile phase.
• Versatility: These columns can be used for a wide range of applications, including the analysis of pharmaceuticals, environmental samples, and other complex mixtures
• Good Peak Shape: The base deactivation helps to minimize peak tailing (broadening of peaks) for basic compounds, leading to better resolution and quantification.
• Alternative to other base-deactivated phases: The Exsil ODS-B columns are often compared to other popular base-deactivated phases like Hypersil BDS.
• Alternatives: They are often used as an alternative to classical spherical HPLC silicas and can be a good substitute for Spherisorb columns.
• Exsil 100: Columns with a pore size of 100 Å Angstroms (10 nm)
