Introduce Your Sampling Canisters to Restek® Air Valve Excellence (RAVE™)

The new RAVE™ valve 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.

Now standard on our full line of SilcoCan®, TO-Can®, and miniature air sampling canisters, these newly redesigned, 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.

Abstract: In order to make GC column installation easier when using an insulating cup in your Agilent® split/splitless GC inlet, standard reducing nuts should be replaced with extended reducing nuts. This simple change improves visibility of the nut during column installation and allows you to reap the benefits of using the insulating cup.

Restek and the Shimadzu Institute Set to Collaborate on GC Basics Training

International GC Specialist Jaap de Zeeuw will be giving two educational presentations about the basics of gas chromatography at the Shimadzu Institute for Research Technologies, University of Texas at Arlington:

Optimize the GC for the Analysis of Traces in Environmental Arena: Practical tips to recognize key contributors affecting sensitivity

Keith Irwin, Restek’s Texas and Louisiana territory manager, will also be on-hand. In addition to gaining invaluable training from one of the industry’s experts, attendees can meet Keith face-to-face, arrange a site visit, or further discuss how Restek can help you solve your analytical challenges.

Restek is excited to collaborate with Shimadzu, the University of Texas, and their new educational institution. We encourage our customers, colleagues, and partners in Texas and beyond to attend.

The Effects of LC Particle Choice on Column Performance: 2.7 vs. 5 µm Diameter Superficially Porous Particles (SPP)

Year of Publication: 2014


Abstract: Restek’s Raptor™ LC columns feature superficially porous particles (commonly referred to as SPP or “core-shell” particles) and are available in both 2.7 and 5 µm particle sizes, giving analysts greater flexibility. However, it may not always be clear which particle size to choose. In this technical note, we will examine the differences in efficiency, sensitivity, and pressure between Raptor™ LC columns packed with 2.7 vs. 5 µm particles and provide advice on making the appropriate LC particle choice.
