Thermo Fisher Scientific will exhibit food-safety solutions at the fourth International Symposium on Recent Advances in Food Analysis (RAFA) in Prague, Czech Republic, 4-6 November, 2009.
Products will include the Exactive high-resolution mass spectrometer, the 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 fast and precise monitoring of potentially harmful contaminants in food and feed.
The Thermo Scientific TSQ Quantum GC triple quadrupole mass spectrometer offers high sensitivity and selectivity, using H-SRM to reduce matrix interference.
The Thermo Scientific Exactive is a benchtop LC/MS system offering high resolution, accurate mass and fast scanning capabilities for 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 and is fully compatible with U-HPLC.
For high-throughput requirements, the Thermo Scientific Transcend is an independent, parallel, multi-channel U-HPLC system that enables automated sample preparation at the speed of multidimensional chromatography.
The Transcend TLX system with TurboFlow technology is designed to automate sample preparation and maximise throughput while providing higher sensitivity for the detection of food contaminants at low levels.
TurboFlow automated sample preparation technology reduces overall analytical time compared to traditional offline methods, such as liquid-liquid or solid-phase extraction, while minimising 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 5 November at 12.45pm.
During this 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 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 characterise 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 unit.
