IMPAQ C18 is the traditional matrix for reversed-phase chromatography. The high loading provides the highest degree of hydrophobicity commercially available. Considered as the least selective phase since it interacts with a wide range of organic molecules.
SiliaChrom® dt C18 has the same unique technology phase as SiliaChrom AQ C18, but the purity of the spherical silica gel is 99,999%, the highest value for HPLC SiliaChrom Series.
