*Maximum temperatures listed are for shorter length columns. Longer columns may have a different maximum temperature.
• General-purpose columns for drugs, solvent impurities, pesticides, hydrocarbons,
PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles.
• Temperature range: -60 °C to 350 °C.
• Equivalent to USP G27 and G36 phases.
The diphenyl dimethyl polysiloxane stationary phase is the most popular GC station-
ary phase and is used in a wide variety of applications. All residual catalysts and low
molecular weight fragments are removed from the Rtx®-5 polymer, providing a tight
monomodal distribution and extremely low bleed.
