• Abstract: The number and type of atmospheric pressure techniques suitable for sampling analytes from surfaces, forming ions from those analytes, and subsequently transporting those ions into vacuum for interrogation by mass spectrometry has rapidly expanded over the last several years. Moreover, the literature in this area is complicated by an explosion in acronyms for these techniques (e.g., DESI, DART, DAPPCI, PADI, DeSSI, AP-MALDI, LAESI, ELDI, etc., etc.), many of which provide no information relating to the chemical or physical processes involved. In this presentation I will sort this vast array of techniques into a relatively few categories on the basis of the approaches used for surface sampling and ionization. For each technique, I will explain, as best known, many of the underlying principles of operation, describe representative applications, and in some cases, discuss needed research or advancements and attempt to forecast their future analytical utility. When possible I will highlight an area with recent results from our own research program.

• Bio:
Gary J. Van Berkel, the group leader of and senior research scientist in the Organic and Biological Mass Spectrometry Group at Oak Ridge National Laboratory, earned his B.A. in Chemistry from Lawrence University (Appleton, WI) and his Ph.D. in Analytical Chemistry from Washington State University (Pullman, WA). His research focuses on the fundamental aspects of atmospheric pressure ion sources for mass spectrometry and on the novel configuration and application of these ion sources to solve analytical problems. His most notable work over the past decade lead to a elucidation of the electrochemical aspects of electrospray ionization. More recently he and his group have been investigating and developing atmospheric pressure surface sampling/ionization instrumental techniques and methods for high throughput analysis and chemical imaging with mass spectrometry.
