SilcoSmooth Stainless Steel Separate permanent gases, including carbon monoxide and carbon dioxide, without cryogenic cooling. Rapid separations of permanent gas/light hydrocarbon mixtures. Excellent compatibility with most GC detectors—minimal bleed, minimal baseline rise. Preconditioned, less than 30 minutes to stabilize. Maximum temperature of 280 °C/300 °C.

By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. What are ch…

low-polarity proprietary phase

(fused silica PLOT)

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane.

Proprietary Crossbond diphenyl/dimethyl polysiloxane phase

General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns. The bonding mechanisms produce a col…
