GC Capillary Column Rtx-5, 15 m, 0.53 mm ID, 0.25 µm with 10m Integra-Guard Column

Innovative Integra-Guard® Columns

Get the protection without the connection!

• These innovative columns incorporate both guard column and analytical column in a continuous length of tubing, eliminating the connection and all connection-associated problems!
• The guard column section is marked separately from the analytical column, using high-temperature string.
• A wide variety of our Integra-Guard® capillary columns are available.

Similar Phase(s): DuraGuard, EZ-Guard, Guardian

Rtx®-5 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.
• Temperature range: -60 °C to 350 °C.
• Equivalent to USP G27 and G36 phases.
• Similar Phase(s): HP-5, DB-5, CP-Sil 8 CB, ZB-5 NOTE: DB-5MS is a silarylene-based polymer, similar to Rxi-5Sil MS.

The diphenyl dimethyl polysiloxane stationary phase is the most popular GC stationary 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 mono-modal distribution and extremely low bleed.
