Environmental Analysis New Generation of Gas Chromatographs
At the 23rd Analytica Trade Fair for Laboratory Technology and Analytical Conference, Bruker (USA) announced the release of its new generation gas chromatography platform – the SCION™ Series Gas Chromatographs.
Utilising the Innovation with Purpose Strategy, the new SCION 436-GC, and the SCION 456-GC set a new standard for data acquisition speed, >600 Hz per channel. This key advance increases productivity and provides a platform that will inspire further advancement of GC separation technology. Every SCION GC series comes standard with a 9 inch, multi-language touch-panel designed for full GC operation in 13 different languages, making it truly a global instrument. Dr. Frank Laukien, President and CEO of Bruker Corporation commented, “The launch of the new generation SCION 436 and 456 Gas Chromatographs reaffirm our commitment to providing innovative new products to the gas chromatography market. Continuing from the incredibly successful SCION TQ and SQ products, the new SCION GC’s set the stage for even more innovations from Bruker in this key market segment.”
The SCION 436-GC is a compact 2 injectors, 2 detectors, platform that supports all the injectors and detectors including mass spectrometry – a perfect choice when bench space is at a premium. The SCION 456-GC provides industry-leading flexibility by supporting 3 injectors and 4 detectors, including the mass spectrometer. Meredith Conoley, Director of GC Marketing, added, “The SCION 456-GC is the industry’s first system to be able to simultaneously acquire data from 4 detectors including a mass spectrometer, providing our users a rapid time-to-benefit advantage.”
Mr. Collin D'Silva, President of the Bruker Chemical & Applied Market (CAM) division, remarked: "The launch of our new generation Bruker SCION Gas Chromatographs coupled to our Pittcon 2012 launch of CompassCDS C/S sets the standard for high-productivity GC analysis, making the SCION platform one that’s focused on results."

Analytical Method for Accurately Determining the Percentage Content of Polyfluorinated Compounds
Exeter Analytical (UK) has developed a reliable analytical method for accurately determining the percentage Carbon (C), Hydrogen (H) and Nitrogen (N) content of polyfluorinated compounds (PFCs).
Polyfluorinated compounds are extremely thermally and chemically stable and have soil, water and fat-repellent properties. They are nearly non-biodegradable and accumulate in the environment and the food chain. Due to their specific technical characteristics - polyfluorinated compounds are used in quite a number of products such as in textiles, carpets, cosmetics, paper, packaging materials as well as in general in the chemical synthesis, metallation, photo and semi-conductor industries.
Generally compounds containing fluorine can be successfully analysed for percentage CHN content on an elemental microanalysis system under standard operating conditions. The magnesium oxide in the combustion tube reagent packing absorbs fluorine as HF, and releases the hydrogen. However, polyfluorinated samples, which are often difficult to combust, can give incorrect low carbon and high nitrogen data.
For these highly fluorinated compounds, Exeter Analytical have developed a new reliable analytical method based upon their Model 440 Elemental Analyser.
Benefiting from a horizontal furnace design, the Exeter Analytical Model 440, allows analysts to routinely and simply produce accurate and precise data on wide ranging sample types without system re-optimisation, saving precious time and reducing running costs.

Ocean Optics' (Netherlands), Vivo NIR Source is a compact, tungsten halogen light source for VIS-NIR spectroscopy across the 360-2000 nm range. Compatible with all Ocean Optics spectrometers, optical fibres and sampling accessories, Vivo delivers powerful output for reflection and other measurements. The high powered source is ideal for use in NIR analysis of pharmaceuticals, grains and oils, as well as food safety applications.
Vivo’s four tungsten halogen sources, arranged for reflection measurements at a 90 degree angle to the detection fibre, can be turned on and off for precision control. The powerful bulb output enables shorter spectrometer integration times than conventional methods-as fast as 1ms with some system setups. An inner cooling fan reduces the risk of overheating the sample to ensure accuracy.
The Vivo can be attached to Ocean Optics’ RTL-stage or other standard for stability and control. Powered by an included universal power supply, the Vivo’s tungsten halogen bulbs are rated for 2,000 hours.
