Mike HindsMike Hinds <hinds@mint.ca>

He received his Ph.D. in Analytical Chemistry from the University of Saskatchewan (Saskatoon, Canada) in 1988. In the same year, he joined the Royal Canadian Mint as an Assay Chemist. Mike implemented many new methods using a variety of spectrometric techniques to analyse a range of precious andnon-precious metal samples. He has been developing methods using XRF spectrometry since 1999. His expertise also includes mass measurement and dimensional metrology. His duties include acting as consultant for both Ottawa and Winnipeg facilities for solving measurement problems and spectrometer purchases. He continues to be involved with the fabrication and characterization of all manner of in-house standards and reference materials for precious metal analysis.

Professional Activities

Maggi LoubserMaggi Loubser <Maggi.Loubser@gmail.com>

Her 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 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 involve the development of training material, training, mentoring and capacity building of the chemists in the group.  She has 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 SeyfarthAlexander Seyfarth

Alexander 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 were 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 new the Sr. Global Product Manager for Hand Held XRF for BRUKER Elemental in Kennewick WA USA. This allows him to directly influence and drive product development and the quest for more performance and capabilities in the pXRF segment! Since 2004 he has been involved with The University of Western Ontario XRF Short Course and also is involved in presenting various seminars and courses throughout North America. Please contact him for any course marcom related issues!

Dr. Bruno Vrebros Bruno Vrebos <bruno.vrebos@panalytical.com>

Dr. Bruno Vrebros is currently a senior scientist for X-ray fluorescence at PANalytical in the Netherlands.  He obtained his degree in Metallurgy and Materials Engineering at the Katholieke Universiteit Leuven in 1981 and his Doctorate in engineering at the same university in 1986.  At PANalytical he is involved in the development of hardware and software for X-ray fluorescence spectrometers.  He is also on the Advisory Board of X-Ray spectrometry.  He begins instructing UWO XRF course since 2007.

James P. WillisJames P. Willis, Emeritus

Professor James Willis was an analytical scientist and environmental geochemist at the University of Cape Town, the Department of Geochemistry and later the Department of Geological Sciences from 1961-2000.  Ha was appointed to Professor Emeritus at UCT in 2000. He has experience in many analytical techniques, but specialized in XRF spectrometry applied in geological and environmental samples, including lunar and terrestrial rocks and soils, sediments, coal and fly ash.  Professor Willis was President of the South African Spectroscopic Society from 1986 to 1999.  He received the S.A. Spectroscopic Society’s ARLABS Gold Medal in 1986; a Geological Society of South Africa’s Honours Award for contributions to analytical geochemistry in 1992, and the Denver X-ray Conference Birks Award in 1994.  James taught XRF courses at UCT since 1974 and at UWO from 1990 to 2005.   Presently he works as an XRF consultant.

Charles Wu <ctwu@uwo.ca>

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. Recently, in 2007, he was appointed to manage the Earth Sciences Module of the UWO's Biotron Experimental Climate Change Research Institute.

He has extensive experience in 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.
