The 007-5 phase is a (5% phenyl) methylpolysiloxane polymer. Like the 007-1 dimethylpolysiloxane phase, the 007-5 phase is a widely used general purpose GC phase that is ideal for a wide range of applications. The presence of the phenyl groups results in induced dipole interactions that lead to an increased level of retention for aromatic solutes. A 5% phenyl substitution causes a nominal increase in polarity; however, the 007-5 phase exhibits the characteristics of a nonpolar phase. The nonpolar 007-5 phase, which separates compounds by boiling point, is another commonly used phase type in GC. Bonding and cross-linking of this general purpose GC phase increases resistance to purge degradation, large solvent injections, and non-volatile deposition. The 007-5 phase offers excellent efficiency and thermal stability. In addition, this non-polar phase is less susceptible to oxidation and hydrolysis than phases with more polar functional groups.
