GRS-1701 GC Capillary Columns
GRS-1701 is a (14% cyanopropylphenyl) methylpolysiloxane phase. The cyanopropyl functional groups provide a permanent dipole selectivity different from the induced dipole interactions of the phenyl groups. The overall "polarity" of this phase remains nominal when compared to the more highly cyanopropyl substituted phases such as GRS-225 and GRS-23. The GRS-1701 phase is often used for solvents, pharmaceuticals, derivitized sugars and many environmental applications.
