007-1701 is a (14% cyanopropylphenyl) methylpolysiloxane phase. The cyanopropyl functional groups provide permanent dipole selectivity that is distinct from the induced dipole interactions of the phenyl groups. The overall "polarity" of this phase remains nominal compared to the more cyanopropyl-substituted phases such as 007-225 and 007-23. The 007-1701 phase is commonly used for solvents, pharmaceuticals, derivatized sugars, and many environmental applications.Pokaż więcej
