Thermo Fisher Scientific Inc. today announced the availability of a method to detect melamine and cyanuric acid in food matrices. The method uses Thermo Scientific instrumentation for liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) systems, and is published in the U.S. FDA’s Laboratory Information Bulletin No. 4396, May 2007. Melamine is an industrial chemical used in the manufacturing of plastics, flame retardants and other products. Recent news coverage about the presence of melamine in infant formula, cookies and candy has once again raised public concern about the chemical in the food supply chain for both animals and humans. This latest finding comes roughly one year after the announced presence of melamine and cyanuric acid in pet food.

The LC-MS/MS method utilizes the Thermo Scientific TSQ Quantum triple quadrupole mass spectrometer coupled to a Thermo Scientific Surveyor MS pump and autosampler. Thermo Scientific Xcalibur data system software was used to acquire and analyze the data.

Thermo Fisher Scientific has also published a related application note (Thermo Scientific Application Note 424 – May 2008), “Analysis of Melamine and Cyanuric Acid in Food Matrices by LC-MS/MS.” This application was developed on the TSQ Quantum Ultra in collaboration with the National Center for Food Safety and Technology at the Illinois Institute of Technology, Chicago, Illinois. Currently this method is being used as a reference by the labs under Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) in China to develop an LC-MS/MS method using TSQ Quantum systems for the detection of melamine in milk and infant formula.

The Thermo Scientific TSQ Quantum triple quadrupole system is the only instrument that enables highly-selective reaction monitoring (H-SRM), which facilitates the quick and efficient analysis of complex samples such as food matrices and animal tissue. Additionally, the Thermo Scientific solution, when coupled to TurboFlow technology, has the advantage of providing a total solution from on-line sample preparation to data analysis, saving scientists and regulatory agencies valuable time.

Finnigan TSQ Quantum Series

Thermo Fisher Scientific

The Finnigan TSQ Quantum Series of mass spectrometers are the most advanced and powerful triple quadrupole mass spectrometers available. The Quantum Series mass spectrometers feature the patented HyperQuad™ mass analyzer technology, a rugged orthogonal source, and a completely redesigned analyzer geometry for maximum sensitivity, precision, and reliability. The Quantum Series triple quads are the only commercial triple quads available today capable of performing H-SRM. Thanks to H-SRM, co-eluters with nominal masses that vary by 0.1 amu are no longer interfering ions. Product detail: The NEW Finnigan TSQ Quantum Discovery MAX: Extraordinary Value The high-performance, ultra compact benchtop Finnigan TSQ Quantum Discovery MAX incorporates innovative new technology for increased sensitivity, precision, ruggedness, and reliability. It is principally designed for high-productivity environments such as environmental, clinical and drug discovery laboratories. With the Ion Max source, the Finnigan TSQ Quantum Discovery MAX addresses the need of these laboratories for more rugged and dependable LC/MS/MS to enable around-the-clock productivity. The combination of our patented HyperQuad™ mass analyzer system, high efficiency ion transfer optics, and outstanding ion source roboustness provides precise accurate quantitation even at the lowest levels. The Finnigan TSQ Quantum Ultra EMR™: Peerless Versatility Thermo introduces the newest addition to its Finnigan TSQ Quantum Ultra series of triple quadrupole mass spectrometers, already established and recognized for its standard of excellence in mass spectral quantitation. The Finnigan TSQ Quantum Ultra EMR™ offers higher resolution and an Extended Mass Range of up to 3000 Daltons. This extended mass range capability allows high-resolution analysis of a whole new class of biopolymers including peptides, polysaccharides, and oligonucleotides. It combines all the benefits of the Finnigan TSQ Quantum Ultra, including constant neutral loss, parent scanning, high-resolution precursor ion selectivity, and Selected Reaction Monitoring, to deliver a complete solution for the proteomics and large molecule research community. The Finnigan TSQ Quantum Ultra™: Definitive Performance The Finnigan TSQ Quantum Ultra defines a new standard of excellence in bioanalytical and environmental analysis.  It features the revolutionary Ion Max source with interchangeable ESI and APCI probes and a wide aperture titanium skimmer for increased robustness and sensitivity. Its large volume ion transfer tube provides enhanced ion transmission, resulting in increased sensitivity. The Ion Max source allows probe adjustment in the x, y, and z directions, for optimum sensitivity and robustness. The Finnigan TSQ Quantum Ultra’s new, ultra-high temperature APCI probe with ceramic heater technology, virtually eliminates sample carryover. Its innovative technology provides the widest linear dynamic range and highest sensitivity of any triple quadrupole mass spectrometer. The Finnigan TSQ Quantum Ultra AM™: Unrivaled Capabilities The Finnigan TSQ Quantum Ultra AM has the additional capability of routine accurate mass measurement on the chromatographic timescale, to facilitate compound identification. It contains a meticulously redesigned analyzer control board, which takes full advantage of the HyperQuads™, and permits accurate mass measurements to within ±5 ppm. This innovation imparts accurate mass measurement performance that is easier to use and have a greater dynamic range than those of instruments based on hybrid quadrupole/time-of-flight technology.
