ToF-SIMS and other surface spectroscopies applied to the study of ancient artifacts: Preliminary investigation of a tetradrachm of Claudius
Feb 05, 2018
(a) Obverse and (b) reverse view of coin # DN 107 from the Diniapoulos collection, Queen's University.
The Ontario Centre for the Characterisation of Advanced Materials at the University of Toronto published a paper about the application of ToF-SIMS, XPS, EDX to investigate ancient coins. The coins are part of the Diniacopoulos collection of Central and Eastern Mediterranean antiquities housed at Queen's University.
In this first study protocols were developed to gain information on the composition and distribution of the various chemical components at the coins surfaces and bulks. In a second study it is hoped that by comparing the results on the different coins, information on how the coins were made can be elucidated. This information could then be used to develop the most appropriated conservation treatment and preservation strategies. If you would like to read the full paper please go to:
Obituary for Professor Alfred Benninghoven
Jan 08, 2018
With deep sorrow we announce that Professor Dr Alfred Benninghoven passed away on Dec 22, 2017 at the age of eighty-five.
With Alfred Benninghoven, the SIMS community loses one of its most notable pioneers. He influenced the development of static SIMS like no one else and laid the scientific foundation for the successful, worldwide spread of the technique.
After studying physics in Paris and Cologne he started to work in the group of Professor Fritz Kirchner, a well-known German nuclear physicist, at the University of Cologne. In 1961 he graduated and received his post-doctoral lecture qualification in 1965. In 1973 he became a professor for experimental physics at the University of Muenster and held this position until his retirement in 1997. During this time, more than 160 master and PhD students graduated from his group and over 300 papers were published under his supervision.
Alfred Benninghoven was a passionate and gifted scientist. The basis of his success, along with his impressive creative power and expertise, was a remarkable determination and professionalism, which made him one of the leading pioneers in the SIMS field for nearly half a century. His book “Secondary Ion Mass Spectrometry: Basic Concepts, Instrumental Aspects, Applications, and Trends”, published in 1987 together with Professor Friedrich Ruedenauer and Professor Helmut Werner, is still regarded as a crucial source of reference.
In 1977 he set up and organised the first international SIMS conference at the University of Muenster. He acted as chairman of this well-established conference until SIMS XV. He was also very active as a thorough editor for the SIMS proceedings. In 1981 he initiated and organised a second biennial conference with the focus on ion formation from organic solids (IFOS). The subject of the conference was the rapidly developing field of ion formation from involatile, thermally labile organic compounds. The event was held in Muenster until IFOS IV. In 1999, he initiated the successful series of biennial European SIMS conferences in Muenster and was head of the local organising committee until 2008.
Alfred Benninghoven was also recognised and decorated for his engagement in different research organisations. He was president of the German Vacuum Society from 1977 to 1983 and received the Gaede-Langmuir Award of the American Vacuum Society for the development of concepts and instrumentation in static secondary ion mass spectrometry and the demonstration of its usefulness in manifold applications in 1984. The development of ToF-SIMS instrumentation and applications was acknowledged by the German Ministry of Education and Research with the Technology Transfer prize in 1988. He was also awarded the Fritz-Pregl-Medal of the Austrian Society of Analytical Chemistry in 1990.
In 1989 he founded the company IONTOF together with his co-workers Dr Ewald Niehuis and Thomas Heller, in order to commercialise the original research carried out at the University of Muenster.
In 1997 he was a co-founder of Tascon GmbH, a testing laboratory specialised in Time-of-Flight SIMS, managed by Dr Birgit Hagenhoff.
Despite all his achievements Alfred Benninghoven always remained a modest and approachable person. He will be remembered as a great researcher, teacher, mentor and important dialogue partner.
Our deepest sympathy goes to his family and friends.

New HITEC Research Project at the Forschungszentrum Jülich
Dec 04, 2017
HITEC, the international graduate school in energy and climate research, is a joint initiative between Forschungszentrum Jülich, the RWTH Aachen University, the Ruhr-University Bochum, the University of Cologne, the Heinrich Heine University Düsseldorf, and the University of Wuppertal. It is committed to scientific excellence, to an interdisciplinary and international research environment, to an accepting learning environment which embraces diversity, and aims to turn the Ph.D. students into well needed experts for academia and industry.
The target of the new research project #6, about 3D tomography of Li distribution in all-solid-state battery materials, is to fully exploit new SIMS capabilities in combination with the available atom probe analysis for advanced, multi scale tomography to investigate the elemental distribution, especially Li, in state of the art all-solid state battery materials, components and cells.

Research Project #6
Innovative molecular imaging instrument at NPL provides new insights into drug discovery and cell biology
Nov 14, 2017
Nature Methods published a paper written by Dr Melissa K Passarelli and Prof Ian S Gilmore from the National Centre of Excellence in Mass Spectrometry Imaging (NiCE-MSI) at the National Physical Laboratory (NPL) highlighting the unparalleled capabilities of the exciting new 3D OrbiSIMS. The paper gives a comprehensive overview of the remarkable performance and the potential of the new instrument for label-free imaging of drugs and metabolites which can be seen as a major step in realising the dream of super-resolution metabolic imaging.
Following Prof Ian S Gilmore original idea, IONTOF and Thermo Fisher ScientificTM developed the 3D OrbiSIMS in close cooperation with the National Centre of Excellence in Mass Spectrometry Imaging (NiCE-MSI), GlaxoSmithKline, and the School of Pharmacy of the University of Nottingham.
In the last few years it has become apparent that for a successful application of SIMS in life science, excellent imaging performance in combination with highest mass resolution, extreme mass accuracy and high-resolution MS/MS are essential. The 3D OrbiSIMS combines the strengths of high-speed ToF imaging with the high mass-resolving power, high mass accuracy and MS/MS capability of the Q ExactiveTMHF from Thermo Fisher ScientificTM and has the potential to provide critical insight on fundamental biological processes.
With the new Hybrid SIMS, a combination of the TOF.SIMS 5 and the Q ExactiveTMHF, IONTOF now offers a commercial version of the 3D OrbiSIMS.
