Restek offers a full range of porous polymers, including HayeSep and Porapak polymer packings for analyses of volatile compounds and light solvents.

Midpolarity crossbond phase general-purpose columns for alcohols, oxygenates, PCB congeners (e.g., Aroclor mixes), pesticides, and fragrance compounds. Equivalent to USP G46 phase.

A low- to midpolarity phase application-specific columns for volatile organic pollutants. Recommended in U.S. EPA methods for volatile organic pollutants. Temperature range: -20 °C to 240 °C. Equivalent to USP G43 phase. The unique polarity of the Rtx-624 column makes it ideal for analyzing volatile organic pollutants. Although the Rtx-502.2 column is recommended in many methods, the Rtx-624 column offers better resolution…

A low- to midpolarity phase general-purpose columns for residual solvents, alcohols, oxygenates, and volatile organic compounds. Equivalent to USP G43 phase.   Many analysts feel the Rtx-1301 column has the best cyanosiloxane bonded stationary phase available, with no other column manufacturer providing lower bleed, longer lifetime, or better inertness. The polymer is fully characterized to ensure long-term reproducibili…

A highly polar phase; biscyanopropyl polysiloxane—not bonded Stationary phase selectivity optimized for isomer separation to ensure accurate quantification of critical cis/trans FAMEs. Application-specific QC test guarantees consistent, reliable performance for AOAC 996.06 and AOCS Ce 1j-07 methods. Excellent sample capacity; no peak distortion means easy, accurate peak integration. Temperature…

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)

Thermo Scientific™ TraceGOLD TG-5SilMS GC Columns incorporate phenyl groups in the polymer backbone for improved thermal stability, reduced bleed and reduced susceptibility to oxidation.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane.

Proprietary Crossbond diphenyl/dimethyl polysiloxane phase

By switching to the unique selectivity of ZB-Dioxin you will gain enhanced resolution of 2,3,7,8-TCDD and 2,3,7,8-TCDF from its isomers in one run, and only need a single ZB-Dioxin GC column as your SINGLE column solution for Dioxin analysis. Upgrade your existing GC column for Dioxin analysis to a Zebron ZB-Dioxin GC column and get all the analytical benefits and productivity gains of a single column solution.

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…
