  • Mass spectrometry is a very important analytical method used in practically all chemistry laboratories the world over.

    Press Release: The Nobel Prize in Chemistry 2002

  • Mass spectrometry is a very widely used method for small and medium-sized molecules.

    The Nobel Prize in Chemistry 2002

  • Doping and drug tests, foodstuff control and environmental analysis are examples of areas where mass spectrometry is now in routine use.

    Information for the Public - The Nobel Prize in Chemistry 2002

  • Levin has been regularly measuring carbon-14 content in air samples from Germany using a version of a Geiger counter, but Tans and other researchers have recently turned to accelerator mass spectrometry, which is faster and easier to scale up.

    Scientific American

  • Mass spectrometry, which is most sensitive in the low molecular weight range, is now a tool used to explore these modified protein molecules and has already revealed a vast number of previously unknown biomarkers. - medical news plus CME for physicians

  • The Lab uses cutting-edge techniques of gas chromatography-mass spectrometry and nuclear magnetic resonance imaging for metabolite analysis and clinical diagnoses.

    Metabolic testing laboratory

  • These include metabolite measurements for plasma, urine and cerebrospinal fluid amino acids using ion exchange chromatography, urine organic acids using gas chromatography/mass spectrometry, and total and free carnitine levels and quantitative acylcarnitine profiles using electrospray tandem mass spectrometry.

    Laboratory Rotation

  • Like flow cytometry, gas chromatography and gas chromatography-mass spectrometry, the technologies used to detect the presence of the chemicals used in the production of plastic, are well established.

    The Explainer: Plastics

  • I find it hard not to raise a quizzical eyebrow when I hear about the initiatives of the avant garde such as champagne house GH Mumm's quest to find the perfect dishes to match with its very good non-vintage champagne, where "gas chromatography, solid phase micro-extraction and mass spectrometry" were all brought to bear on this most urgent of questions.

    The best wine and food matches

  • A critical new facility is our triple-stage tandem mass spectrometry unit which allows for the mass screening of dozens of different inherited metabolic disorders.
