- EC HPLC column (analytical), NUCLEODUR C18 Isis, 5 µm, 250x4.6 mm
Isis (from ancient Greek) is a goddess of Egyptian mythology. Within the divine realm, Isis played a very special role - she was the only goddess with magical powers. The NUCLEODUR C18 Isis is a octadecylsilyl phase with special polymeric, crosslinked surface modification and allows exceptional steric selectivity. This "magical" selectivity can separate (o,p,m-) substituted aromatics.
