Online Mass Spectrometry Seminars
Upcoming seminar:
Date/Time: September 25, 2025 / 1300 UTC
Topic: Analysis of Residual Pesticides in Crops, Surface Soil, Honey and Heavy metals using GC-MS and AAS Methods
Pesticide residues analysis was carried out on surface soil of agricultural plot utilized by peasant farmers within the university environment in Makurdi metropolis (Latitude 070 410N, longitude980 370 E) as well as in honey obtained from Jos, Plateau state, Nigeria. Pesticide residues were determined using Gas Chromatography-Mass Spectrometry (GC-MS, Hewlett Packard 7890A series II) equipped with a 63Ni electron capture detector. Maximum and minimum total rainfall (mm) were obtained. Mean concentration (µg/kg) of pesticides in combined vegetables (Telfairia occidentalis, Solanum macrocarpon and Capsicumanuum) were calculated. Some heavy metals were detected in honey samples from Jos.
Presenter: Peter Onuwa (Joseph Sarwuan Tarka University, Makurdi, Benue State, Nigeria)

Why? When? Who? What?
The inspiration behind the establishment of this online mass spectrometry seminar platform was driven by our passion for the subject and wish to share with as wide an audience as possible. The platform facilitates academics, engineers and enthusiasts to share their research and mass spectrometry experience with others across the Globe.
The seminar sessions are free to attend, to start with, speakers will be invited to share their work, however, members are most welcome to apply to present and join the program. Audience participation is encouraged and there will be a question-and-answer session at the end of each seminar.
Dr. Giles Edwards FRSC
Giles is a fellow of the Royal Society of Chemistry and has been working with mass spectrometry systems since 2000 in various capacities. These include at present consultancy with Anthias Consulting Ltd, development of a novel mass spectrometry platform and contract analysis with Artemis Analytical Ltd as well as working in the nuclear physics group at the University of Manchester. Giles also founded the Recycling Organisation for Research Opportunities in 2005 that donates refurbished mass spectrometry systems to academics in developing countries, everyone needs a mass spectrometer.
Dr. Hendrik Kersten
Hendrik´s background is physical chemistry (teaching and research) and he has been playing around with all kinds of mass spectrometers in various fields of application since 2007. He is head of the institute for pure and applied mass spectrometry (ipaMS) at the University of Wuppertal, organizes workshops in fundamental mass spectrometry and implemented a two semester module in the chemistry master with two lectures and a lab course covering the broad interdisciplinary field of mass spectrometry.
