by SiliCYCLE
SiliaChrom XDB1 phases present the wider range of polarity of SiliCycle HPLC columns (C18 to normal phase). This phase presents the maximum bonding density for all polarities. This allows least interaction between the analytes and the surface OH's. This phase is not recommended for samples containing highly hydrophobic compounds.
SiliaChrom® XDB1 C18-300 reverse phase functionalization is completely identical to the XDB1 C18 equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.
