About RAVE Valves

Restek Air Valve Excellence (RAVE) brings proven long life, leak-free performance, and effortless operation to your air sampling canisters. This durable design has been engineered to exceed 15,000 cycles—and every valve is leak-tested with helium to 1×10-6 mL/sec before it leaves our facility. The W-type valve seats are work-hardened to enhance damage resistance, while the wetted surfaces contain no moving parts. And because convenient, reliable field use isn’t just about withstanding the rigors of harsh environments, the RAVE valve achieves full closure with a quick twist of the fingers (only 10 in-lb) and is easy to access, even for big hands or when wearing bulky gloves.

Standard on Restek’s full line of SilcoCan, TO-Can, and miniature air sampling canisters, these American-made valves are also ideal for upgrading existing canisters. Rugged stainless steel RAVE valves can be ordered with Siltek treatment for added inertness and either 2 or 3 ports to accommodate an optional gauge. Plus, diaphragm rebuild kits are available to further extend the life of these long-lasting air valves.

Simplify the Switch to HILIC with Raptor HILIC-Si Columns

Restek is bringing the speed and reliability of Raptor LC columns into the HILIC realm with the addition of the Raptor HILIC-Si column. HILIC is an increasingly popular alternative to reversed-phase LC for challenging polar analytes because it provides better retention of water-soluble compounds that are separated by polar differences. The Raptor HILIC-Si column simplifies the switch to HILIC because it delivers rugged Raptor performance, provides SPP column speed for faster analyses than traditional FPP silica columns, retains polar compounds without ion-pairing reagents, and is fully reliable, efficient, and selective with LC-MS compatible mobile phases.

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 without expensive UHPLC instrumentation. Learn more about Raptor LC columns at www.restek.com/raptor

Rugged, reliable Raptor HILIC-Si columns make the analysis of polar compounds fast, easy, and MS friendly!

Set Your Sights on Superior Performance with Restek PAL SPME Arrow and Test Mix

SPME Arrows and Test MixTraditional SPME fiber technology has some significant drawbacks including poor mechanical stability and a small phase volume. The Restek PAL SPME Arrow system is a revolutionary change in microextraction that combines exceptional robustness with faster extraction times and trace-level sensitivity. In contrast to traditional SPME fibers, SPME Arrows contain significantly more phase volume, which allows more target analyte to be extracted in less time, significantly increasing sample throughput. In addition, the stainless steel construction, unique Arrow tip, inner stabilizing rod, and outer sheath design fully protect the phase, minimizing both analyte loss and mechanical damage. Use with our new SPME test mix to ensure performance after each installation. This mix is a certified reference material (CRM) with verified composition and stability.

Analyze CO and CO2 at ppb Levels Easily and Accurately with a Restek Methanizer

Low-level detection of carbon monoxide (CO) and carbon dioxide (CO2) is critical for many applications. Restek’s methanizer (CH4izer) for Agilent GCs allows ppb-level determination of CO and CO2 using a cost-effective FID instead of more expensive instrumentation. The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO2 to CH4, but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point and the actual temperature is shown in real time on an easy-to-read display. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement so you spend more time analyzing samples and less time on maintenance.
