Markes and ALMSCO International to Jointly Showcase High-Sensitivity Technology for Trace-Level Aroma and Fragrance Profiling at PittCon 2012
Markes International Ltd together with its mass spectrometry division, ALMSCO International, have jointly announced that they will be showcasing their latest suite of products for trace-level organic chemical analysis at PittCon 2012. These market-leading technologies for sample preparation, thermal desorption (TD) and time-of-flight (TOF) mass spectrometry for gas chromatography will be exhibited on stand 1780.
On show will be the newly-released CIA Advantage™ TD system for automated and cryogen-free analysis of VOCs in air or gas canisters alongside Markes’ state-of-the-art technology for manual and automated thermal desorption of tube-based samples. The booth will also feature Markes’ increasingly popular Micro-Chamber/Thermal Extractor™ ( -CTE™) sample preparation accessory to complement our TD range, The - CTE provides a versatile quick screening tool for volatile and semi-volatile organic chemicals (VOCs and SVOCs) emitted from manufactured goods and raw materials and is also used extensively for fragrance and aroma profiling.
Offering reference-quality full spectral information at traditional SIM detection limits ALMSCO’s high-performance TOF mass spectrometer, BenchTOF-dx™, promises to be a highlight of the show. Combining selectivity, stability and speed with full spectral sensitivity, this unique instrument delivers high-definition mass spectrometry and outstanding performance for every GC application. Rugged and robust for routine operation BenchTOF-dx, is also more than equal to the challenges of advanced research. It offers identification and measurement of both target compounds and unknowns in highly complex matrices and at the lowest possible levels.
Completing the suite of products on display will be ALMSCO’s pioneering data mining software, TargetView™, for automated identification and measurement of trace target compounds in highly complex GC/MS profiles.
“The combination of these technologies is particularly useful to those involved in the GC analysis of trace level components in highly complex mixtures” says Alun Cole, Markes’ CEO. “By using Markes and ALMSCO technologies side-by-side, we’re able to provide ‘multi-hyphenated’ solutions for a wide range of GC/MS applications, and at Pittcon 2012, we’ll be show-casing this using food aroma profiling as an example”.

New Data Demonstrate the
Value of Zetasizer µV in Protein SEC Two new, free to download, technical notes from Malvern Instruments describe the function and benefits of using the Zetasizer µV as a detector for size exclusion chromatography (SEC), focussing on its suitability for protein characterisation. Capable of dynamic (DLS) and static light scattering (SLS) detection, the compact Zetasizer V simultaneously measures absolute
size and molecular weight, maximising the information produced by each measurement to increase experimental productivity. The OmniFACE connection interface from Malvern Instruments enables the Zetasizer µV light scattering detector to be readily integrated into any third party size exclusion chromatography (SEC) system.
www.malvern.com/TechNote-Zetasizer-connection details how to connect the Zetasizer µV to users existing SEC system to enhance functionality. It explains how to make the necessary fluidic and electrical connections to the chromatograph, OmniFACE and the Zetasizer µV to begin data collection. Examples illustrating connection to the most popular SEC systems are provided.
www.malvern.com/AppNote-Zetasizer-Protein describes the advantages of using the Zetasizer V for SEC measurements in the characterisation of proteins. These include: automated operation to give both protein size and molecular weight, complete integration with the SEC software, rapid switching between batch and chromatography modes, and a low volume flow cell to minimise band-broadening.
