Rtx-5MS—Low-Bleed GC-MS Columns (fused silica)

low-polarity phase; Crossbond diphenyl dimethyl polysiloxane
  • General purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles.
  • Column specifically tested for low-bleed performance.
  • Temperature range: -60 °C to 350 °C.
  • Equivalent to USP G27 and G36 phases.
  • Some dimensions also available as Integra-Guard columns — a guard and analytical column in one to eliminate connection problems!

Rtx-5MS columns are coated with a 5% diphenyl/95% dimethyl polysiloxane phase and are tested to rigorous specifications for low bleed and high inertness. They have polarity identical to Rtx-5 columns, but exhibit lower bleed.

Rxi-5Sil MS columns are coated with a silarylene phase that exhibits polarity very similar to a 5% diphenyl/95% dimethyl polysiloxane phase, but the phenyl rings in the polymer chain of the silarylene phase impart improved thermal stability and lower bleed. The Rxi-5Sil MS column is an ideal choice for analyzing EPA Method 8270 semivolatile pollutants. The slight difference in the selectivity of Rxi-5Sil MS columns also improves separation of polycyclic aromatic hydrocarbons (PAH), such as benzo[b]- and benzo[k]- fluoranthene isomers.

Note: The DB-5MS is a silarylene-based polymer equivalent to the Rxi-5Sil MS.
