The International Symposium on Advances in Extraction Technologies (ExTech) is an important event series in the growing fields of sample preparation, extraction technologies, and sample clean-up techniques. The conference was started in 1999 by Professor Janusz Pawliszyn (University of Waterloo, Canada), and since then it has been held annually in different cities around the world.
This year is the 25th edition and ExTech 2023 will be held in Tenerife (Canary Islands, Spain) from 18–21 July 2023 at Pirámide de Arona Conference Centre, located at Playa de Las Américas (Tenerife South).
The organizer of the conference this year is the University of La Laguna (ULL, Spain), with Professors Verónica Pino and Javier Hernández‑Borges as chairwoman and co-chairman, respectively.
The ExTech2023 programme will cover analytical separation, analytical (micro)extraction, sample preparation techniques, and their hyphenation with chromatography, mass spectrometry, and related techniques.
The symposium starts with a full-day course on microextraction, and is followed by three days of plenary and keynote lectures, oral communications, and vendor seminars. Professor Pawliszyn, Professor Pedersen-Bjergaard (University of Oslo, Norway), Professor Anderson (Iowa State University, USA), and Professor Cárdenas (University of Córdoba, Spain) will present plenary lectures. Poster and vendor exhibitions will be hosted during the whole conference.
Key dates include: deadline for oral presentations: 1 March 2023; deadline for poster presentations: 1 June 2023; early registration until: 15 April 2023; late registration until: 30 June 2023.

Detangling the Complex Web of GC×GC Method Development to Support New Users
September 12th 2024The introduction of comprehensive two-dimensional gas chromatography (GC×GC) to the sample screening toolbox has substantially increased the ability to comprehensively characterize complex mixtures. However, for many gas chromatography (GC) users, the thought of having to learn to develop methods on a new technology is daunting. Developing a basic GC×GC method for most (nonspecialized) applications can be accomplished in minimal time and effort given parameter suggestions and ranges to target analytes in a sample of interest. In this article, the authors work describe a simple workflow to develop a GC×GC method for a specific sample upon initial use, with the aim of decreasing the time to accomplish functional workflows for new users.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Two-Dimensional Supercritical Fluid Chromatography System Created with Multiple Heart-Cutting Modes
September 11th 2024Université d’Orleans and Chromisa Scientific scientists recently created a two-dimensional supercritical fluid chromatography (SFC) system with multiple heart-cutting (MHC) modes.
