007-5, (5% PHENYL) METHYLPOLYSILOXANE

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 ideal for a broad range of applications. The presence of the phenyl groups provides induced dipole interactions leading to degrees of increased retention for aromatic solutes. A 5% phenyl substitution causes a nominal increase in polarity; yet the 007-5 phase displays the attributes of a non-polar phase.

The non-polar 007-5 phase, which separates compounds according to boiling point, is another frequently used phase type in GC. Bonding and crosslinking this general-purpose GC phase increases the resistance to degradation by rinsing, large solvent injections and the deposition of non-volatiles. 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 incorporating more polar functional groups.
