The 007-1301 is a (6% cyanopropylphenyl) methylpolysiloxane phase.  Overall, 007-1301 is a low polarity phase which exhibits excellent thermal stability.  The cyanopropyl (permanent dipole) and the phenyl (polarizable) substituents provide a specific selectivity for polar and polarizable compounds.  More of a boiling point phase than 007-1701 (14% cyanopropyl phenyl methylpolysiloxane), the 007-1301 exhibits less retention of polyaromatic compounds than 007-17 (50% phenyl methylpolysiloxane). 

Nitrogen-containing herbicides, various types of pesticides, drugs and other heteroatom-containing compounds are good candidates for separation using this phase.  

As part of the 007 Series of Bonded Phases, the 007-1301 can withstand large solvent injections and rinsing to remove insoluble impurities.
