The 19th International Symposium on Advances in Extraction Technologies (ExTech) took place between the 27th and 30th of June in the historic Spanish city, Santiago de Compostela. This symposium series was started in 1999 by Prof. Janusz Pawliszyn (the University of Waterloo, Canada) and since then has become a unique and vital platform for the exchange of information and ideas in the growing field of sample preparation. The 2017 Symposium featured sessions on fundamental developments and new technologies in extraction and sample preparation relating to different areas of the analytical sciences, with a particular focus on environmental applications, food quality and safety, pharmaceutical and personal care products analysis, bioanalysis and natural product chemistry.
In 2006, the SSG launched a prize for the best poster presented at an ExTech meeting. This year, the SSG awarded three prizes (£200 each) for the best posters presented by junior scientists. An international committee judged more than 200 high-quality poster presentations, on topics including new extraction techniques, environmental sampling and sample preparation, bioanalytical extractions,and food and flavour analysis. Three posters were selected for the 2017 SSG award on the basis of their outstanding scientific content and presentation in the poster format:
- Joana Carvalho’s poster on the Optimisation of a DNA purification protocol by micro-scale solid phase micro-extraction and microfluidics for food products on a washable and reusable device. Ms Carvalho is currently a PhD student, working on the development of a micro-Total Analysis System for food and environmental analysis at the International Iberian Nanotechnology Laboratory (INL) in Braga (Portugal), in collaboration with the University of Santiago de Compostela (Spain).
- Emanuela Gionfriddo’s poster on the Coupling solid phase micro-extraction to complementary separation platforms for metabotyping of E Coli metabolome in response to natural antibacterial agents. Dr Gionfriddo is currently a Research Associate in Prof Janusz Pawliszyn’s group and manager of the gas chromatography section of the Industrially Focused Analytical Research Laboratory (InFAReL) at the University of Waterloo (Canada).
- Priscilla Porto Figueira from the University of Madeira, Portugal, for her poster on Micro-speed: A new and powerful micro-extraction in food analysis – Isolation of phenolic compounds in teas as a case study
Congratulations to our prize-winners! And we hope to see many more excellent posters at next year’s ExTech meeting, which will be held in Ames, Iowa (USA) in June 2018. See you there!
