Elise Dennis (27) is the recipient of the Best Paper Award 2014, presented by the Springer journal Analytical and Bioanalytical Chemistry (ABC). In a paper published in ABC, lead author Dennis and her colleagues demonstrate the performance of a new concept called zoom-time-of-flight mass spectrometry (zoom-TOFMS). The award, accompanied by 1,500 euros, was created by Springer to honor exceptional young scientists and to stimulate their research careers. The ABC Best Paper Award has been given since 2005.

Dennis's study demonstrates the unique advantages of alternating between constant-momentum acceleration and conventional, constant-energy acceleration, which include an improvement in mass resolution without a loss in instrument sensitivity. The new method is expected to be amenable to retrofitting onto existing time-of-flight mass spectrometers.

Elise Dennis received her B.S. with honors from the College of William and Mary (USA) and is currently a Ph. D. candidate in analytical chemistry at Indiana University Bloomington (USA) under the direction of Prof. Gary M. Hieftje. Her work pushes the boundaries of time-of-flight mass spectrometry with studies into the effects of constant momentum acceleration on the mass separation process.

Professor Klaus Heumann, Editor of ABC, said: "This is an excellent contribution to the further instrumental development of TOFMS where a new mass spectrometer concept was demonstrated. By combining two types of TOFMS (zoom-TOFMS and DOFMS), complete mass-spectral coverage and enhanced resolution is provided which makes this development a highlight in mass spectrometry."


Analytical and Bioanalytical Chemistry's mission is the rapid publication of excellent and high-impact research articles on fundamental and applied topics of analytical and bioanalyti¬cal science. Its scope is broad, encompassing the entire range of analytical and bioanalytical research and encouraging multidisciplinary solutions to problems in this field. ABC counts among the leading journals in its field and is partly owned by eight prestigious chemical societies.

Springer Science+Business Media is a leading global scientific, technical and medical publisher, providing researchers in academia, scientific institutions and corporate R&D departments with quality content via innovative information products and services.

The article "Zoom-TOFMS: addition of a constant-momentum-acceleration 'zoom' mode to time-of-flight mass spectrometry" by Elise A. Dennis, Alexander W. Gundlach-Graham, Steven J. Ray, Christie G. Enke, Charles J. Barinaga, David W. Koppenaal and Gary M. Hieftje is freely available online at or can be requested as a pdf.
