The triple quadrupole mass spectrometer has become the most common mass spectrometer in the world today, with sales of over $1 billion per year. It is today the gold standard for quantitative analysis in metabolomics, clinical analysis, drug discovery and development, environmental analysis, and a wide variety of other application areas. That invention, by Professors Yost and Enke, along with related research in their labs, has helped propel mass spectrometry into the one of the most commonly used analytical methods in the world.
