The Puritas Eximius represents a high performance ODS phase based on a new generation of silica gel developed to show long peak retention and high loadability, as a result of its exceptionally high surface area.
The ODS bonding density is chosen with respect to optimal selectivity for both hydrophilic and hydrophobic compounds, enabling even the use of 100% aqueous eluents. Our proprietary end capping technology minimizes residual silanol groups amount below the detectable level. This result in very good peak symmetry, particularly in case of basic compounds and exhibits high chemical phase robustness.
Puritas ODS series is available with particle sizes of 2.1, 3, 5, 10 and 15 microns for both analytical as well as preparative applications.
