Thermo Fisher Scientific Presents Innovative Solutions in Food Safety at RAFA 2009
News Nov 03, 2009
Thermo Fisher Scientific Inc. will exhibit innovative food safety solutions at the 4th International Symposium on Recent Advances in Food Analysis (RAFA) in Prague, Czech Republic, November 4-6, 2009.
Featured products on Thermo Scientific booth #2 will include the exciting Exactive high resolution mass spectrometer, the TSQ Quantum GC with highly selective reaction monitoring (H-SRM) and the Transcend automated sample preparation system, along with equipment, consumables and software that address the need for monitoring of potentially harmful contaminants in food and feed.
Pesticide residue monitoring requirements are increasing and maximum residue limits are decreasing, creating a need for instruments capable of high sensitivity and selectivity. The Thermo Scientific TSQ Quantum GC triple quadrupole mass spectrometer addresses this need using the power of H-SRM to reduce matrix interference, enabling high selectivity and low limits of detection.
The Thermo Scientific Exactive is a benchtop LC/MS system offering unmatched high- resolution, accurate mass and fast scanning capabilities for confident screening and quantification of contaminants in complex food and feed samples. With fast scanning and positive/negative mode switching, the Exactive provides sub-ppm mass accuracies at resolutions of up to 100,000.
Fully compatible with U-HPLC, the instrument is designed for solving the demanding analytical challenges while also being easy to use.
For high-throughput requirements, as in a contract testing lab, the Thermo Scientific Transcend is a truly independent, parallel, multi-channel U-HPLC system to combine the power of automated sample preparation with the speed of multidimensional chromatography.
The Transcend TLX system with patented TurboFlow technology is designed to automate sample preparation and maximize throughput while providing higher sensitivity for the detection of food contaminants at extremely low levels. TurboFlow automated sample preparation technology reduces overall analytical time compared to traditional offline methods, such as liquid-liquid or solid-phase extraction and it minimizes matrix interferences in LC/MS analysis of food samples.
Thermo Fisher will also host a lunch seminar at RAFA 2009 entitled "New approaches to solving emerging food safety issues", which will be held on November 5th at 12:45 pm. During this informative session, speakers will present the benefits of high-resolution mass spectrometry for screening analysis of mycotoxins in food, high-sensitivity multi-residue pesticide analysis in foods using GC/MS/MS and an automated screening method for beta-agonists in urine.
In addition to technical posters on well-established GC/MS and LC/MS technologies, posters will be presented on isotope ratio technology. Stable Isotope Ratio Analysis (SIRA), Bulk and Compound-Specific Isotope Analysis (BSIA and CSIA) are used to investigate food authenticity and origin. SIRA has been used to characterize alcoholic beverages, meats, wines, olive oils, bergamot oils and vanilla extracts for food adulteration and origin studies.
The technology makes it possible to test if honey is pure or has been adulterated with cane sugar and if a juice has natural citric acid derived from fruit juices or from sugar cane or corn syrup. A poster will also be presented on the Thermo Scientific GC IsoLink, which is coupled to an isotope ratio MS within one easy-to-use unit.
Thermo Fisher provides methods-based consulting and applications support in addition to a comprehensive line of products. Thermo Scientific solutions enable fast testing of potentially harmful contaminants in food including chemical residues, fungicides, natural toxins, pathogens, pesticides, dioxins, trace elements and veterinary drugs.
