Lecture I:

R. Graham Cooks, Purdue University

Chemical and Materials Synthesis with the Mass Spectrometer

Location: Carnegie Mellon University, Department of Chemistry, Mellon Institute, 4400 Fifth Ave. Conference Room on the 3rd floor, Enter from Bellefield Street.

Free and open to the public.

Host: Mark E. Bier


The presentation deals with preparative mass spectrometry—the use of the ionization and separation methods of mass spectrometry to prepare macroscopic amounts of material. These experiments include bimolecular reactions in confined volume solutions (such as electrosprayed droplets or thin solution films) which have been scaled up to produce tens of mg amounts of chemical products which are characterized by NMR, SERS, and by analytical MS. This new solution-phase ion chemistry is readily incorporated into undergraduate teaching labs because it is performed with ordinary solvents in the ambient environment and closely resembles conventional solution-phase chemistry, except for its much accelerated time scale. The rates, mechanisms and intermediates are discussed for typical reactions like Girard derivatization, Claisen-Schmidt condensation, Hantzsch synthesis and Negishi coupling. Ion soft landing and ion/surface reactions are shown to allow novel chemical species to be deposited at surfaces, chemical patterns to be written on surfaces and surface-enhanced Raman films to be prepared.

This talk sketches recent rapid progress in mass spectrometry as an analytical method, focusing on its use in intrasurgical tissue analysis (tumor margins and tumor types) and in point-of-care diagnostics (therapeutic drug levels in blood). These two areas of endeavor form the basis for an enquiry into mass spectrometry as well as its relationship to analytical chemistry and to spectroscopy.

R. Graham Cooks, the Henry Bohn Hass Distinguished Professor at Purdue University

R. G. Cooks is a chemist who obtained his first Ph.D. in 1965 from the University of Natal, South Africa and his second Ph.D. from Cambridge University, United Kingdom in 1967 where he also did post-doctoral research. He next joined Kansas State University from 1968-71 as an Assistant Professor and then went on to Purdue University where he has been a professor for 40 years. Prof. Cooks is a MS instrumentation and chemical methods developer and has made tremendous contributions in MS/MS, quadrupole ion trap MS, SID, soft landing MS, DESI and miniature mass spectrometers. He is the recipient of 40 patents, has over 950 publications, has started four companies at Purdue, and helped establish the Center for Analytical Instrumentation at Purdue. In 2012 he received the Ferst Award for mentoring Graduate Students and has advised over 128 graduate students.
