The GERSTEL tradition is to supply a steady stream of innovative solutions for chromatography sample handling and sample introduction, providing increased performance and improved system ruggedness. “Our philosophy is to exceed our customers’ expectations”, says Eberhard G. Gerstel, President and co-owner of the company. GERSTEL has been in the fortunate position to have sufficient resources to keep and extend our strong position as a global provider of GC/ MS solutions while adding LC and LC/MS solutions to our product offering over the past years. Since 1998, GERSTEL has had double digit annual growth; our organization has grown by more than 100 % over the past 5 years. GERSTEL, Inc., based in Baltimore, MD and GERSTEL KK, based in Tokyo, have both contributed strongly, expanding their service and support departments and adding further staff to meet increased demand. A series of products and solutions, including most recently Automated SPE and automated Dynamic Headspace (DHS), have been developed around the GERSTEL MultiPurpose Sampler (MPS). The MPS is an integrated autosampler and liquid handling robot. This year at PittCon, GERSTEL showed the new DHS system and the unique automated SPE system based on standard cartridges. Accelerating Performance The GERSTEL SPE can significantly increase productivity and throughput of GC/MS and LC/MS labs, improving Return on Investment (ROI) for the instrumentation. Additional benefits are improved precision and significantly reduced solvent consumption with associated savings and improvements of the laboratory environment. “Our integrated solutions and integrated software help control every step of the process, from automated Sample Prep through Sample Introduction to control of the entire LC/MS or GC/MS system. Just one method and one sequence table controls the entire process providing simple and efficient operation with less risk of error“, says Eberhard G. Gerstel. GERSTEL management is in a mood to celebrate. In 2007, the company is celebrating its 40th anniversary and the relocation to new larger headquarters.

GERSTEL Solutions Worldwide Portrait In 2005, world-wide production of beer amounted to a volume of around 160 billion liters – or 1.6 billion hectoliters in brewery-lingo; more than half of this sea of beer was produced by the ten largest international brewing conglomerates. Breweries up their R & D investments Improving sales by focusing on quality and consistency In first position, the Belgian InBev group produced around 20 billion liters of beer, almost 13 % of world-wide production. In second place was SABMiller of the UK with 17.6 billion liters, narrowly relegating the US-based brewing giant Anheuser- Busch (17.4 billion liters/year) to third position. In 13th position we find Asahi, Japan’s largest and internationally most successful brewery. Asahi was founded in 1887, launching their first lager beer five years later. In 2005, Asahi produced around 2.5 billion liters, equal to 1.5 % of world-wide production. The trend is clear: further growth! Research Pays Off Asahi’s consistent success and solid growth over many decades is attributed in large measure to the company’s constant commitment to research and development (R&D), which is always striving to produce the best possible product. The Asahi R&D Department has around 300 employees, a relatively large number. The picture that has emerged is, that in order to gain ground and stay among the leaders in international beer markets, breweries must be in a position to develop products that are attractive to a large number of different consumer markets, they must hit the right taste for these budding markets, and last but not least, deliver consistent quality. Analysis Techniques In the Asahi breweries and in their R&D facilities, even though a wide range of analytical techniques are used, chromatography is the technique most commonly used. GC and LC systems help control all stages of production of the many Asahi beverages, ensuring product quality and consistency. These techniques are used for development purposes as well. Chromatography is used “first when we develop the products, for example, analyzing hop flavors; secondly when we work to improve the quality of existing products; and thirdly, in our QC and food safety controls, for example, when we work to eliminate offodors or variations in product taste or try to identify what causes these things”, says Mr. Toru Kishimoto of the Asahi Brewing Research and Development Laboratory. Choosing the Right Sample Preparation Technique Extraction of target compounds from complicated beer or wort matrices is often a challenge. Conventional sample preparation techniques often are not up to the task, according to Mr. Kishimoto: “They re- Mr. Toru Kishimoto talking to Mr. Hirooki Kanda. Mr. Kanda is Managing Director of GERSTEL K.K., a GERSTELsubsidiary based in Tokyo, Japan. quire large volumes of solvent, lots of time, do not provide sufficient recovery or detection limits - and often they cannot be efficiently automated”. Consequently, Asahi has replaced many conventional sample preparation methods with Solid Phase Micro Extraction (SPME) and Stir Bar Sorptive Extraction (SBSE) using the GERSTEL Twister®. Toru Kishimoto: „These techniques are easy to perform. They require no solvent, provide low detection limits, they are fast so they ensure good sample throughput and are easily automated“. SBSE is used by Asahi for the determination of hop flavor compounds as well as trans-2-nonenal, fatty acids or off-odors. Asahi currently has a range of GERSTEL solutions in their laboratories: MultiPurpose Sampler (MPS)-GC/MS systems are used for automated SPME and SBSE analysis. Thermal Desorption (TDS)-GC/MS systems are used for automated thermal desorption of Tenax-filled desorption tubes, MPS/GC-GC/MS systems are used for Multi-Dimensional GC analysis and the GERSTEL Preparative Fraction Collector (PFC) is used for preparative GC. Finally, GC/MS systems fitted with GERSTEL Olfactory Detector Ports (ODP) provide simultaneous olfactory and mass spectrometric detection, using an integrated voice recognition software package to provide a detailed “olfactogram” that includes odor intensity, retention time and voice comments for compounds as they elute.
