Usually, silica based stationary phases for HPLC are grafted with monofunctionnal silane, but recently, studies have put in evidence the effect of grafting mixed functions on the silica surface, a C18 function and a shorter chain (C8, amide, CN, nitro-phenyl, etc). These new products offer different selectivity, coordinated multi-functionality, as well as a spacer effect (C18/C8). Why limit yourself? With SiliCycle, push the limits!
Balance the hydrophobicity of the surface with a C18 function and a shorted hydrocarbon function C8 which play the role of a spacer.
Conjugate the hydrophilic power of the amide functions with the hydrophobic power of the C18 functions for your HPLC applications with our mixed mode C18/amide SiliaChrom® columns.
Conjugate hydrophobic and aromatic interactions with the mixed mode C18 and phenyl chromatographic stationary phases.
Conjugate the separation power of the C18 and the CN functions in a same stationary phase with our mixed C18/CN SiliaChrom® columns.
Separate ionic and hydrophobic compounds at the same time. No more need for pairing agent or using columns in series. Gain in efficiency and time by using mixed mode SiliaChrom® HPLC columns.
