GRS-10 GC Capillary Columns
GRS-10 (10% phenyl substitution, respectively) is the GRS designations of phenyldimethylpolysiloxane phases. The phenyl substitutions contribute to the "induced dipole" selectivity of these phases. A column coated with either phase displays excellent efficiency and thermal stability. These phases provide an excellent alternative for drug and environmental pollutant analyses where greater retention of aromatic compounds is necessary.
- Bonded and crosslinked
- Comparable to: OV-3, OV-7
- Similar phases: Rtx -20, SPB-20
- USP Phase Specification: G32
007-10 Phenyl Methylpolysiloxane columns are available in all standard column I.D.'s and column lengths.
