Maggi Loubser  < Maggi@LondonXrayConsultingGroup.com>

Maggi LoubserHer career in X-ray Fluorescence Spectroscopy started as a laboratory technician at the Atomic Energy Corporation of South Africa in 1988.  There she learned XRF in a process control laboratory. 

During this time she studied part-time towards a BSc in Chemistry, which she obtained in 1996 from the University of South Africa (UNISA), and a BSc (hons) in 2003 from University of Pretoria, and a MSc in Chemistry (University of Pretoria) (2010) with a dissertation entitled:  Chemical and physical aspects of Lithium borate fusion.

In 1994 she joined the Geology department of the University of Pretoria (UP) where for the next fourteen years the X-ray laboratory was build up to a state of the art facility presenting annual short courses in XRF and Representative Sampling and Sample Preparation. 

Since 2005 Maggi has been the presenter at the annual XRF Short Course at University of Western Ontario in Canada. In 2013 she was invited to teach at Yale at a “XRF Boot camp for art conservators.”

She joined PPC Cement in November 2008, where her duties involved the development of training material, training, mentoring and capacity building of the chemists in the group.  She had the responsibility to ensure world-class analytical laboratory practices at PPC’s laboratories, manage compliance to laboratory minimum standards and identify and implement best practices in the analytical laboratories. Since October 2014 she was also heading the R&D department leading a group finding innovative ways to address the challenges of a fast-changing cement manufacturing environment.

She started her own consultancy GeoMag GeoChem April 2016 to be able to live out her passion in assisting laboratories across the continent to set up their methods optimally, carrying over knowledge and experience to a wider audience of chemists and having the time to get involved in interesting projects.

Alexander Seyfarth   < Alexander@LondonXrayConsultingGroup.com >

Alexander SeyfarthAlexander Seyfarth is an x-ray spectroscopist with over 20 years of experience with XRF and XRD. Alexander holds a Master degree in Mineralogy from University Giessen (1996). Thesis work for his graduate studies was done on chemical and phase investigation of kiln deposits using XRF, EPMA, and XRD as well as Rietveld structure refinement on isolated phases. Widely traveled within Europe and the Americas, he has worked onsite to install, commission and calibrate systems ranging from Semiconductor and Cement to Mining sites.

Training users has been part of his professional career from PC training in the early 80s to XRF in more recent years. Since 1990 he has been using XRD and XRF techniques and instrumentation as part of the research and teaching of assistants at the University Giessen. Starting in the early eighties he advanced as a computer buff from a ZX81 to PC's, running a PC-based consulting and services business on the side from 1986.

From the 1996 Freelance and Contract work for ceramic and cement companies within Germany, he moved in January 1997 as Application Scientist XRD and XRF to SIEMENS AXS in Karlsruhe. In December 1998 he transferred to Madison, WI as Application Scientist XRF, XRD at BRUKER AXS. A vertical move brought him in 2003 from Senior Application Scientist XRF and Product Support XRF to Customer Service. From 2006 to 2011 he was the Product Manager XRF North America for BRUKER.

After a too short stint as Sr. Application Scientist for the ARL brand with THERMO SCIENTIFIC in Madison, he was recruited as the new Sr. Global Product Manager for Hand Held XRF for BRUKER in Kennewick WA USA. This allowed him to directly influence and drive product development and the quest for more performance and capabilities in the pXRF segment! Having completed the successful introduction of the TITAN and new TRACER5i he changed from the vendor into a user function as the new Global Technical Manager for XRF with SGS Minerals.

He was taught by James Willis when he started with Siemens and has been involved with the course since 2004 as a teacher and marketing support.  Maggi Loubser and he are also teaching the XRF Bootcamp organized by Getty and Yale for Art Conservators.

He is acting Chief Operation and Marketing Officer of the London X-Ray Consulting Group LLC and in charge of the licensing and technical content of training materials. 


 Charles Wu   < Charles@LondonXrayConsultingGroup.com >

Charles Wu Dr. Wu's experience with x-ray fluorescence spectrometry began in the early 80's while working towards the completion of his doctoral thesis. Having been conferred a PhD in Geology from The University of Western Ontario in 1984, he lectured for several years in the topics of optical mineralogy, metamorphic petrology, and igneous geochemistry. In 1988, he accepted a position as Lab Manager and Research Scientist running the Earth Sciences Department's Analytical Geochemistry Laboratory. In 2007, he was appointed to manage the Earth Sciences Module of the UWO's Biotron Experimental Climate Change Research Institute. He retired from the University at the end of 2016. 

He has extensive experience in the instrumental analysis in the use of XRF, AA, INAA, ICP-AES, and IC. Since 1990, Dr. Wu has organized the UWO XRF Course that has trained and educated hundreds. He is now Chief Executive Officer of the London X-Ray Consulting Group LLC.

Technical Advisor

James P. Willis <jwcc@iafrica.com>

JPWProf Emeritus James Willis worked in the Departments of Geochemistry and Geological Sciences at the University of Cape Town (UCT) from 1960 to 2000, during which period he also gained his Masters (with distinction) and Doctoral degrees. He was initially employed as a research assistant rising through the ranks to Associate Professor in 1981.

On his retirement from UCT in 2000 he was appointed professor emeritus in the Department of Geological Sciences. He was a N.A.S.A. co-investigator for the Apollo lunar sample studies in the late 1960s and early 1970s, a visiting scientist at the Max Planck Institüt für Chemie (Abteilung Kosmochemie), Mainz in 1982, a member of the central committee of the South African Spectroscopic Society from 1974-1999 and its president from 1986 to 1999. He was also a council member of the South African Coal Ash Association from 1987-1993. In 1986 he received the S.A. Spectroscopic Society's ARLABS Gold Medal, a Geological Society of South Africa Honours Award (1992), and was the fifth recipient of the prestigious international Denver X-ray Conference Birks Award in X-ray Spectrometry (1994).

He is an excellent teacher and taught courses on instrumental analytical techniques, sedimentary geochemistry, environmental geochemistry and the theory and practical aspects of Geodata Analysis (statistics). He initiated and co-directed a highly successful taught one­­­-year Masters degree course in Environmental Geochemistry (six months lectures, 5 months dissertation) (1994-2000). From 1974 to 2015 he directed at UCT an annual intensive two-week course on the theory and practice of XRF Spectrometry for university staff and mining and manufacturing industries. The course was also given at the Department of Geology, University of Western Ontario, London, Ontario from 1991-2005. He started a bi-annual Elementary XRF course at the Central Analytical Facility at University of Stellenbosch in 2010.

Over the years he gained experience in many analytical techniques, starting with DC arc optical emission spectrometry (using glass photographic plates to record the spectra!), atomic absorption spectrophotometry, electron microprobe analysis, SEM-EDX, instrumental neutron activation analysis, ICP-AES, ICP-MS, HPIC, particle size analysis, X-ray diffraction , and XRFS. He has a very broad experience in many different fields of geochemistry, including sedimentary and environmental geochemistry, meteorites, marine geochemistry, sediments, sedimentary rocks, coals and fly ash.

He describes himself as a geochemist with a strong interest in the development, promotion and application of spectroscopic analytical techniques.

Since "retiring" from UCT he has concentrated on writing four technical books on XRF:
