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

Switch to a Raptor HILIC-Si LC column when you need more retention and resolution of hydrophilic, polar analytes. HILIC silica column designed for increased retention of polar compounds without ion-pairing reagents. 2.7 μm Raptor core-shell particles provide the speed of SPP, with greater efficiency and capacity than 5 μm particles. Ideal for increasing sensitivity and selectivity in LC-MS analyses. Fully compatible with both…

Removes up to 135 ml of oxygen or 2 g of water.

For ASE Systems

Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind.

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…

Replacement Part for FID Collector Assembly Kit.

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

Pump PM kit for Agilent 1050, 1100, 1200 HPLC Systems. Includes: PTFE frits (2); outlet cap; gold disk seal; active inlet cartridge; piston seals (4); glass solvent filters (2).

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…

Fit all 2.0 mL, 12 x 32 mm, crimp-top vial-based autosamplers.

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…
