ABOUT US


Allan Fraser & Associates was founded in November 2008. The organisation offers a variety of on-site (your laboratory) courses ranging from sampling, sample preparation, chemical and physical analysis, statistical methods and data treatment. We also provide hands-on training on a variety of analytical methods from wet chemistry to spectrometry. Courses can be customised to suit your laboratory's application.

A consultancy service is provided for laboratories that aspire to achieve the ISO17025 standard of laboratory competence. We provide assistance with method validation, statistical analysis, calibration, method performance and measurement uncertainty. Furthermore, we offer a comprehensive audit of exploration and production geology drilling campaigns to assess the integrity of sampling methods. A comprehensive audit of metal accounting is also offered.


Allan Fraser


Allan Fraser holds a national diploma in analytical chemistry and a master’s degree (M.Sc.) in geology from the University of Johannesburg. He is a former director and board member of PANalytical (Pty) Ltd., South Africa, a position he held for six years. In the early part of his career he worked for Matthey Rustenburg Refiners as a research process chemist.  Following this he spent four years as laboratory manager at Sandvik Hard Materials. Allan then joined LECO Africa as sales engineer gaining ten years of experience in sales of analytical and metallographic instrumentation. Allan also managed three commercial laboratories at Société Générale de Surveillance (SGS), South Africa.

 

In 2008 he founded Allan Fraser & Associates, an organisation specialising in analytical chemistry and geochemical consulting. Allan’s area of expertise is in analytical method development and in the use of statistical methods in analytical chemistry.  He has a good working knowledge of a variety of analytical methods including, LECO combustion, AAS, GF-AAS, and ICP-OES. Allan is member of the following professional organisations: the South African Chemical Institute (SACI), the South African Institute of Assayers and Analysts (now incorproated in SACI) and the Geological Society of South Africa. Allan has been registered as a professional natural scientist with the South African Council for Natural Scientific Professions since 1994.  In February 2018 Allan was registered as a professional chemist (Pr.ChemSA) with the South African Chemical Institute.  

 

He facilitates regular public and in-house courses on statistical method validation for test laboratories and measurement uncertainty. Allan is a signatory as an external validator for African Mineral Standards (AMIS) on certificates of newly generated certified reference materials. 


Mosotho George


Dr. Mosotho George holds a Ph.D. and M.Sc. Degrees in Analytical Chemistry from University of Johannesburg with a thesis titled: Micro-extraction and detection/quantitation of trace pesticides from various matrices as and Advances in single-drop micro-extraction pre-concentration technique, respectively. Under these two degrees the focus has been the development of the affordable sample preparation techniques for gas chromatography and mass spectrometric analysis. These projects entailed in-depth study of the dynamics and application of bubble-in-drop (BID-SDME) solvent micro-extraction format that was developed in our group for extraction of different organic compounds from a range of matrices, ranging from environmental to biological matrices. In total, this work produced six journal articles. Currently Dr. George is a Senior Lecturer and Head of Department of Chemistry and Chemical Technology at The National University of Lesotho where he teaches Analytical Chemistry at all levels as well as supervising research projects across a spectrum of Analytical Chemistry stream. He had a brief spell as Instrument Scientist at University of Johannesburg where he was responsible for manning the chromatography facilities in the Department of Biochemistry at Auckland Park Kingsway campus in 2008-2011, when he returned to Lesotho to assume the lecturing position. He has a vast experience in extraction and analysis of organic compounds from various matrices having supervised and participated in various studies culminating in more than 20 journal articles both credited formally and not. He has authored 15 articles mostly in the use of gas chromatography and mass spectrometry for organic compounds in international peer reviewed journals. He has presented papers in more than 30 international, regional and local fora in topics covering Analytical Chemistry, laboratory management, higher education, science education policy, math and science education, as well as chemical entrepreneurship. Dr. George does contract work for Allan Fraser & Associates in terms of on-site training courses on GC-MS, GC and other separation techniques.

 


Tracey Evans


Tracey Evans holds a master’s degree (M.Sc.) in Biochemistry from the University of Port Elizabeth (Nelson Mandela University). She has analytical expertise and knowledge of a range of analytical methods including ICP-OES, AAS, XRF, MIR, NIR, Leco combustion, Continuous Flow Analysis, Autotitration, HPLC and GC. Tracey started her career at Lennon’s (now Aspen Pharmacare) as a chemical analyst in the QA Lab. She then joined the CSIR as a researcher and project manager, where she managed waste and water projects in industrial processing and chemical manufacturing. A reshuffle of the division saw Tracey back at Lennon’s where she took up a position as section head for analytical method development and validation. Following a period overseas and a move to Durban, she started an IT support, training and web publishing company. When the opportunity presented, Tracey joined the Fertiliser Advisory Laboratory of the South African Sugar Association. As laboratory supervisor for over six years, she was responsible for process optimization (ISO 9001) and quality assurance of all testing methods.

Tracey then joined Pathcare in Cape Town as their ISO 17025 specialist QA coordinator, for their diagnostic and analytical testing testing laboratories around South Africa. She successfully assisted the Veterinary Laboratory to achieve their ISO 17025 accreditation. In her QA role in the Clinical Trials and Veterinary Clinical Trials laboratories, she developed functional GLP and GCP systems. Tracey has proven expertise in analytical method development and validation; documenting and improving systems and auditing management and technical competences. As an independent consultant, she has produced and facilitated several training courses, including method validation and evaluation of measurement uncertainty.

Alan Johns


Alan Johns was born in the United Kingdom and moved to South Africa at an early age. He began his career in coal in 1968 in the laboratory at Athlone power station in Capetown. Alan then moved onto Palabora Mining Company in 1970 as a laboratory technician where he continued coal analysis for the mine power station as well as general mine sample analyses. In 1973 he qualified with a Government Mine Assayers certificate. In 1977 he took up a position as senior analyst at De Beers Diamond Research Laboratory in Johannesburg. In 1981 he joined the TCOA as manager of their Richmond Laboratory, and was promoted to the position of Colliery services manager at their head office in 1985, where he was responsible for monitoring coal quality of export and domestic production from 25-member collieries. With the closure of the TCOA in 1989 he purchased the Richmond laboratory with two partners and ran it as a commercial coal laboratory, and in 1992 was involved with these two partners in setting up Witlab as a commercial venture in Witbank. Witlab was sold to ALS in 2007 and Alan stayed on as technical manager, subsequently taking over the management of the Anglo Coal Central Laboratory when operation of this facility (now called ALS Naledi), was outsourced to ALS in 2010. Alan served two terms as president of the South African Institute of Assayers and Analysts and is an Honourary Life Member of the Southern African Coal Processing Society. Since his retirement in February 2016, he has been consulting to both ALS Witlab and others, on sampling and sample preparation of coal and other commodities, having recently conducted bias testing of a bauxite sampling plant in Guinea and auditing various colliery laboratories in the Witbank area. Alan is an associate with Allan Fraser & Associates and specialises in sampling, sample preparation and analysis.
