The new generation of mixed mode columns from SiELC
Obelisc®
With the increasing demand for the analysis of polar and ionisable compounds, SIELC Technologies have developed Obelisc - their new generation of mixed mode columns.
Obelisc R and Obelisc N are complimentary phases for the separation of polar and non-polar compounds using multiple separation mechanisms (RP, ion-exchange, NP, ion exclusion). Both phases have positive and negative charges separated by a long organic chain, allowing both charges to simultaneously participate in electrostatic interactions.
Obelisc RObelisc N
....for reversed-phase chromatography, with benefits of increased retention of polar compounds....normal-phase characteristics, for polar and charged analytes and for HILIC separations
