The Camille and Henry Dreyfus Foundation has announced that R. Graham Cooks, the Henry Bohn Hass Distinguished Professor of Chemistry at Purdue University, is the recipient of the 2013 Dreyfus Prize in the Chemical Sciences, conferred this year in chemical instrumentation. The international prize, awarded biennially, consists of $250,000, a citation, and a medal. The award ceremony will be held at Purdue University in the fall and will feature a lecture by Professor Cooks.
Graham Cooks is recognized internationally as an innovative giant in the field of mass spectrometry who has enriched analytical chemistry in unparalleled ways. Virtually every pharmaceutical and biotechnology company relies on mass spectrometry at a level that has become possible, in part, through Cooks's innovations.
Mass spectrometry is the science of accurately determining the masses of molecules in a sample from which we can learn the elemental composition of each constituent molecule. Cooks advanced this analytical capability with the introduction of tandem mass spectrometry in which selected ions generated from complex mixtures are further fragmented and the masses of the fragment ions determined. By putting together these pieces of a jigsaw puzzle, a picture emerges of the molecular structure of the parent ion. Cooks has also made groundbreaking advances in ambient desorption/ionization in which ions from a sample at room-temperature in air are introduced into the mass spectrometer for analysis, removing many of the difficulties associated with sample preparation and volatilization in previous, complex mass spectrometric techniques.
In a remarkable accomplishment, Cooks and colleagues have recently created miniature mass spectrometers, enabling the remote deployment of these analytical instruments including under battery power. Mass spectrometers, once roughly as large as an automobile, are now reduced to the size of a shoebox, allowing their widespre
