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.
- Bonded and crosslinked
- Excellent thermal stability
- Moderately polar
- Comparable to OV-11
- Similar phases: DB-35, Rtx-35, SPB-35, AT-35, HP-35, BPX-35
- USP Phase Specification: G42
GRS-35, (35% Phenyl) Methylpolysiloxane columns are available in all standard column I.D.’s and lengths.
