CAMBRIDGE, UK. (January 22, 2009) - Thermo Fisher Scientific Inc., the world leader in serving science, today announced the publication of a new application note demonstrating the capability of the Thermo Scientific iCE 3000 Series AA spectrometers and Thermo Scientific VP100 vapor generation accessory to accurately detect trace levels of mercury in fish. Mercury is a significant environmental toxin that is capable of entering the marine food chain. The consumption of contaminated fish is the main route of human exposure to mercury, which can prove fatal. The application note entitled "Accurate analysis of low levels of mercury in fish by hydride generation AA", gives details of the reagents, sample preparation and instrument conditions needed to accurately analyze low levels of mercury. It is available to download free-of-charge via the literature library at www.thermo.com/ice
Growing concerns about the possible presence of this toxic chemical in the food supply chain have led to tighter restrictions on its presence in the food we eat. Countries and organizations around the world have developed regulations that enforce maximum concentrations of mercury in fish of approximately 0.5 mg/kg wet weight. Coupled with the VP100 vapor generation accessory, the iCE 3000 Series AA spectrometers are capable of reaching detection limits of 0.014 mg/kg. The sensitivity and precision of this configuration easily meets the detection limits detailed in all current international guidelines. Standards in this application were prepared from a 1000 ppm (mg/L) mercury standard solution and the results demonstrated excellent linearity up to 100 ppb, equivalent to 20 mg/kg in a fish sample.
The speed and efficiency of the VP100 allows the analysis of a sample approximately every 90 seconds, while the ease-of-use of the iCE 3000 Series AA allows further method optimization, providing full control over the analysis. In addition, this combination allows users to analyze mercury samples more easily and cost-effectively, compared with more complex and expensive techniques, such as HPLC-ICP-MS or GC-ICP-MS.
The iCE 3000 Series range of AA spectrometers combine high-precision optics and state-of-the-art design to provide unrivalled analytical performance, while the VP100 offers fast, repeatable and robust analysis. The iCE 3000 Series AA operates on the intuitive Thermo Scientific iCE SOLAAR software platform. The SOLAAR software is easy-to-use and gives step-by-step instructions to allow quick set-up and easy optimization of the analyses.
