007-17 is a 50% phenyl methylpolysiloxane phase. The presence of the 50% phenyl groups increases the overall "polarity" of the phase and enhances the selectivity of induced dipole interactions resulting in greater retention of aromatic solutes.

The 007-17 phase is widely used as an EPA Method confirmation column and provides for efficient separations of PAHs, and biomedical samples such as drugs, sugars and steroids.
