GRS-35 GC Capillary Columns

GRS-35 GC Capillary Columns

GRS-35 is the GRS designation for a (35% phenyl) dimethylpolysiloxane phase. This phase is a compromise between GRS-20 and GRS-17 in phenyl content. It is a popular phase for drug analyses; and like the entire series of phenyl-substituted phases, columns coated with the GRS-35 can be rinsed to remove non-volatile and high boiling contaminants.
