2018 Sample Prep Summer Course

Register: Link

The past years have borne witness to a boom in sample preparation. Despite major technological and scientific achievements, most advances have been communicated in the context of “simplicity” and “applications” and led to an associated misconception: “sample prep is simple and there is no theory to it”. Clearly, for many members of the analytical community, there is still not enough clarity on pertinence, process, and practice to answer the one key question - what is truly needed to succeed in sample preparation?
The second meeting of this theoretical and practical sample preparation event focuses on solid- and liquid-phase microextraction. The course has been designed for anyone who is either new to microextraction or wishes to expand current knowledge and understanding about the technique as a whole. During lectures and hands-on training, six leading experts in the field explain why microextraction is more than just a few “simple” procedures. They help participants understand the underlying theoretical principles and teach them how to use these principles for producing better results in the laboratory. The event aims to raise awareness not just to the science that is microextraction and its application, but also the need to achieve erudition at it.
The course starts on Wednesday, the 22nd of August at 9.00 a.m. with Doug Raynie from South Dakota State University, USA, overviewing sample preparation methods and presenting the general principles. Janusz Pawliszyn from University of Waterloo, Canada, then puts solid-phase microextraction on the spot and presents the SPME formats and sorbents next to the theoretical principles underlying each technology. This discussion sets the basis for learning how to face challenges and avoid pitfalls when developing and applying microextraction methods in a laboratory. Elia Psillakis from the Technical University of Crete (Greece) and Stig Pedersen-Bjergaard from the University of Oslo (Norway) then take over and define liquid-phase microextraction and liquid membrane extraction techniques. The principles behind liquid-phase based extraction methods are explained and related to those presented earlier. In the afternoon session, laboratory training is scheduled, and participants get valuable hands-on experience in the fiber-format of SPME and the effect of experimental conditions on SPME performance.
The second-day, lectures start with a more in-depth presentation of SPME. Ezel Boyaci from Middle East Technical University (Turkey) explains method optimization in detail and Gangfeng Ouyang from Sun Yat-sen University (P.R. China) presents the critical stage of calibration. Coverage continues with Barbara Bojko from Collegium Medicum Nicolaus Copernicus (Poland) discussing the approaches to process the different types of samples and shows how to perform specialized tasks like in-vivo sampling. Janusz Pawliszyn concludes these morning lectures by presenting SPME coupling strategies to GC, LC and MS, automation and future directions. After lunch the second laboratory exercise takes place; this time participants get hands-on training in bio-SPME sampling from complex samples and calibration practices.
On the last day, lectures start with Elia Psillakis presenting a variety of two-phase LPME setups. She then uses theoretical models to visualize the extraction process and the effect of experimental conditions on extraction. Coverage continues with common and “new” liquid acceptor phases. Stig Pedersen-Bjergaard then moves the discussion in three-phase LPME, electromembrane extraction and parallel artificial liquid membrane extraction. Lectures conclude with automation potential of liquid-phase based techniques and a discussion on the future directions in the area. At all stages, the sample type and characteristics are taken into consideration next to the “green” and cost-related aspects of each method. The course closes with the last set of laboratory exercises covering a wide variety of two- and three-phase LPME methods.
All lectures and hands-on training takes place at the School of Environmental Engineering, Technical University of Crete, built on a panoramic site in the peninsula of Akrotiri, just a few kilometers outside the city Chania. The island of Crete is the most versatile and exciting destination in Greece. The natural beauty, exquisite archaeological sites and scrumptious and healthy cuisine, attract visitors from around the world. The city of Chania is a place where different civilizations have flourished throughout the centuries. The old town is built around the Venetian port and evidence can be seen from each of these civilizations. It's maze-like alleys with its beautiful Venetian mansions; fountains and elaborate churches offer visitors a plethora of routes to discover. Undoubtedly, the city of Chania provides an inspiring and motivating backdrop to the 2018 Sample Preparation Summer School.
