We are proud to announce that Restek’s own Jaap de Zeeuw was invited to speak at Separation Science 2012 in Kuala Lumpur, Malaysia. Jaap joined chromatography experts from around the globe in presenting his work (see below for the abstract) entitled Application and Limitation of Using Adsorbents as Stationary Phases in Gas Chromatography for the Separation of Volatile Compounds.
Jaap also built on his decades of bench work and three years of solving analysts’ GC challenges as the “ChromDoctor” for Separation Science by participating in a two-hour GC Troubleshooting Discussion Panel with Hans-Gerd Janssen (Unilever) and Philip Marriott (Monash University). Topics of the panel included extending column life time, faster analysis, and use of hydrogen instead of helium.
Of course, Restek was there with a booth where we featured our latest innovations in GC, LC, and sample preparation. In addition, Jaap presented posters on blood alcohol analysis and optimal column selection using USLC® technology.
Application and Limitation of using Adsorbents as Stationary Phases in Gas Chromatography for the Separation of Volatile Compounds
Jaap de Zeeuw, Restek Corporation
Adsorbents are widely used in many petrochemical applications for several reasons. They have high selectivity for dedicated classes of compounds, which allows for short run times; high retention, which allows for higher analysis temperatures; and extreme stability because the retention is based on adsorption, which makes them very durable. When adsorbents are coated into a capillary column, we speak of PLOT-type columns (Porous Layer Open Tubular). Such adsorption layers are formed by particles that need to be concentric and stabilized. Here is also the challenge, as particles can be swept from the wall and cause blockage. Today’s PLOT columns are highly stabilized and perform well in most hardware configurations. They are chosen often for portable and process-type applications where metal capillaries have also found a new application. Developments have been made on alumina, molecular sieve, as well on porous polymer adsorbents. Practical applications and limitations of using adsorbents in GC will be presented and discussed.
Introducing the new face of Restek!
Restek Corporation has announced a major rebranding campaign. From shipping containers and product packaging to literature and the web, the new face of Restek has already started to appear in the marketplace and will continue to spread in the upcoming months. “We are very excited to roll out this new look,” says Director of Marketing Dennis Claspell. “For over 25 years, our customers across the globe have turned to us for reliable solutions to complex chromatographic challenges. This powerfully straightforward, uncluttered new design perfectly matches what Restek stands for in the industry.”
It is important to note that Restek is the same employee-owned company providing innovative chromatography solutions relied on by laboratories worldwide. As the transition is completed, the old branding will still appear on some product boxes until existing supplies are exhausted. However, inside there will always be high-quality genuine Restek products, newly manufactured and packaged with care to meet your chromatography needs.
Product Marketing Managers: Scott Adams (GC Accessories) and Paul Connolly (LC Columns)
Restek recently expanded its marketing department by bringing on two new Product Marketing Managers: Paul Connolly (LC Columns) and Scott Adams (GC Accessories). Paul and Scott will manage day-to-day operations and product maintenance while former PMMs Rick Lake and Kelli Steindl will oversee their respective product lines in the newly created role of Product Line Manager.
Paul brings 24 years of analytical and chromatography expertise to Restek, including 16 years performing LC-MS/MS. He earned his B.S. in Biology and a minor in Chemistry from the University of Pittsburgh, after which he was a Chemist for Halliburton NUS Environmental Services for nearly a decade. Paul has also worked as a Scientist and Principle Investigator, then Group Leader for Centre Analytical Laboratories; an LC-MS Technical Leader for Exygen Research; and a Bioanalytical Director for MPI Research. Additional highlights of his professional experience include sample preparation, pharmaceutical drug development, clinical analysis, animal health/food safety, and method development. As our new LC Columns Product Marketing Manager, Paul’s main focus will be further developing Restek’s USLC® technology into new application areas.
Equipped with a B.S. from The Pennsylvania State University and two years’ experience as an Environmental Chemist at Lancaster Labs, Scott spent 13 years with Alltech Associates/WR Grace, where he worked in research & development, technical support, applications, product management, and e-business. Most recently before joining Restek, he also worked at Thermo Scientific as an Applications Specialist. With a balanced mix of marketing and application proficiency, Scott will be helping expand our offering of GC accessories to better meet the needs of analysts worldwide.
In addition to seeing our GC and LC product lines grow and improve, you will also meet Paul and Scott as they represent Restek at tradeshows, symposia, seminars, and more.

Abstract: Recent work analyzing 1,4-dioxane in drinking water using large volume splitless injection is summarized in this LCGC North America application note. Concurrent solvent recondensation–large volume splitless injection (CSR-LVSI), an alternative to programmed temperature vaporization (PTV), typically requires a special GC inlet. The technique described here uses an unmodified split/splitless inlet with CSR-LVSI to lower detection limits for the analysis of 1,4-dioxane in drinking water. The complete version of this application is also available and can be found here: http://www.restek.com/Technical-Resources/Technical-Library/Environmental/env_EVAN1548-UNV
