GRS-1301 GC Capillary Column

The GRS-1301 is a (6% cyanopropylphenyl) methylpolysiloxane phase. Overall, GRS-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 GRS-1701 (14% cyanopropyl phenyl methylpolysiloxane), the GRS-1301 exhibits less retention of polyaromatic compounds than GRS-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 GRS Series of Bonded Phases, the GRS-1301 can withstand large solvent injections and rinsing to remove insoluble impurities.
