Abstract: In Part I, we discussed possible sources for ghost peaks related to the carrier gas and the gas lines. Here we move into the injection port itself as this is a big source for “trouble”. The injection of the sample is responsible for > 80% of the “troubles” that are experienced in gas chromatography. In the process of rapid evaporation of the sample, several things can go wrong.

Chromatography Mastermind Campaign Earns American Inhouse Design Award

Are You A Chromatography Mastermind?Graphic Design USA has presented Restek Corporation with a 2013 American Inhouse Design Award for its Chromatography Mastermind tradeshow materials. Of the 4,000+ entries submitted each year, only the top 15% gain acknowledgment through this prestigious competition. The GD USA contest “is the original and the biggest showcase for outstanding work by inhouse designers. For many years, it has provided an opportunity for inhouse designers to be recognized for their talent, for the challenges they face, and for their contributions to their businesses and institutions.” Restek is proud to accept this honor and would especially like to applaud graphic designer Barb Roan for her exceptional efforts on this project.

This multi-component Chromatography Mastermind campaign was initially created to publicize Restek’s presence at Pittcon 2013. Specifically, its goal was increasing awareness of the Chromatography Mastermind quiz, which was assembled by technical representatives across the company as a way for customers to test themselves while having fun and learning more about the various presentations being offered at the show. The app, mailer, e-mail, T-shirt, website advertisements, stickers, signage, app, and other pieces were so well received by attendees that the iPad app quiz will now be making an appearance at several other events throughout Restek’s 2013 conference schedule.

If you are a chromatographer looking to test your knowledge with some separation science brain teasers, visit to see where this exclusive app will be challenging analysts next. Restek’s technical experts will also be on-hand to assist you with your chromatography struggles—and of course, Restek products and support are always available at

Inaugural Governor’s ImPAct Award Celebrates Restek for its Export Activities

2013 Governor's ImPAct Awards WinnerOn May 23, 2013, companies from around the state of Pennsylvania converged at the Hershey Lodge for the first annual Governor’s ImPAct Awards. This prestigious event was conceived by Governor Tom Corbett, the PA Department of Community and Economic Development, and the Team PA Foundation to pay tribute to businesses that are creating jobs and actively investing in Pennsylvania. To be eligible, companies first had to be nominated by their representative to the Partnerships for Regional Economic Performance (PREP) program. Then, the merits of each nominee were scored by an independent panel of judges to determine the final winners in each PREP region.

Three representatives from Bellefonte-based Restek Corporation—Shaun Smith, Karen Kishbach, and Nicole Simpson—accepted the Export Impact award on behalf of the employee-owners of Restek. This award comes soon after Restek announced the opening of a new subsidiary in the People’s Republic of China—joining offices in the U.S., France, Germany, UK, and Japan in addition to a distributor network that covers over 100 countries across six continents. As a company that started so humbly in a single room of a business incubator just over 25 years ago, Restek is honored to be recognized for its expansion into a global provider of cutting-edge chromatography products and world-class Plus 1 service.
