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

This highly retentive, highly selective phase—unique to Restek—was developed specifically for the analysis of aldehydes and ketones as DNPH derivatives. Allure AK is a reversed-phase HPLC material that has the unique ability to separate all 13 carbonyl compounds specified in California Air Resources Board (CARB) Method #1004 using a simple acetonitrile/water gradient. Other columns require long analysis times or the use of tet…

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

Certified reference materials (CRMs) manufactured and QC tested in  ISO-accredited labs  satisfy your ISO requirements.

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.

(fused silica PLOT)

UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-resistant pressure regulation. They are more easily purged of atmospheric components compared to brass gas regulators, making them ideal for the most demanding applications. Stainless steel is especially useful in atmospheres of dry corrosive gases such as hydrogen. All regulators are rated to 3,000 psig (20,684 kPa) maximum inlet pressure.…

Rtx-Wax columns are the most inert and efficient PEG columns currently available. The extended operating temperature range allows analysis of compounds having a wide volatility range and ensures low bleed at temperatures as high as 250 °C. Selectivity is comparable to other Carbowax columns for compounds of intermediate to high polarity.

Whether you need to replace system tubing as part of your troubleshooting or want to reduce the dwell volume of your system as you move to narrower columns, Restek has the quality tubing in the lengths and IDs you need. Each ID is color-coded, so it is easy to identify and replace correctly. Tubing is precision cut, resulting in clean, square-cut ends without ovality.

Attach to the column in seconds to form an airtight seal. Increase column lifetime—prevent moisture and air from entering the column during storage. Two styles to choose from: glass or silicone material. Glass caps are color-coded for identifying detector and injector ends. Not recommended for reuse.

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or ""core-shell"" particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane.

Proprietary Crossbond diphenyl/dimethyl polysiloxane phase

Extend column lifetime.

The Allure Acrylamide LC column provides targeted acrylamide retention as well as improved isolation from matrix interferences.
