About Us

In 2019 the idea of ExtraTECH Analytical Solutions was born, to create a spin-off company  that translates scientific discovery in tangible ways to directly benefit analytical laboratories. The company capitalizes from the vast research experience of its team and offers breakthrough sample preparation products and methods that work under vacuum. ExtraTECH Analytical Solutions has developed and globally commercializes a series of patent pending closures for different microextraction technologies. These specially designed closures offer gastight seal to commercial 20 mL headspace vials and allow headspace microextraction sampling under vacuum conditions. The analytical methods offered, ensure fast extraction under mild conditions and at the same time, reduce costs, energy demands and laboratory waste.

ExtraTECH Analytical Solutions  is a member of ELEVATE GREECE, the official platform and leading resource of the Greek startup ecosystem supported by the Greek government. In 2022, the company became a member of EGG’s (enter • grow • go), the most successful business accelerator in Greece ran by EUROBANK in partnership with Corallia. ExtraTECH Analytical Solutions is also an ordinary member of the SEV Scale up Community of the SEV-Hellenic Federation of Enterprises the largest business network in Greece, representing major industrial and important enterprises in Greece.

We have filled the following pending patents for our methods and vial closures:

  • METHODS AND VIAL CLOSURES FOR HEADSPACE EXTRACTION UNDER VACUUM, WIPO, PCT, International Publication Number.: WO 2021/100006 A1 Current stage: regional applications for China and Europe (EPO)
  • METHODS AND VIAL CLOSURES FOR HEADSPACE EXTRACTION UNDER VACUUM, USPTO, Pub. No.: US 2021/0156768 A1 Current stage: under examination

Our Team

Prof. Elia Psillakis

Founder & Director

Elia Psillakis is the Founder and Director of ExtraTECH Analytical Solutions. She was the first to formulate the theory behind the positive effect of vacuum on headspace SPME. She also introduced criteria for predicting the effect and gave new insights into headspace microextraction. She expanded the applicability of the vacuum-assisted methods from SPME fiber to high-capacity sorbents and described the theory behind the additional advantages of adopting the vacuum approach on these sorbents. In parallel to her research studies, she continuously developed new closures offering gastight seal to commercial vials for extended times and during microextraction operations.

Elia Psillakis is also a Full Professor in Water Chemistry at the School of Chemical and Environmental Engineering, Technical University of Crete. She received her degree in Chemistry in 1995 from Universitè Montpellier II, France with Summa Cum Laude, and in 1997 her PhD from the University of Bristol, U.K. In 2007, she received a Fulbright Award and used it at California Institute of Technology (Caltech), USA.

Elia Psillakis was featured in the Power List 2021 of the magazine “The Analytical Scientist” as one of the Top 100 most influential people in analytical science. To date, her investigations have resulted in six book chapters and >100 publications in ISI Journals that have received >8200 citations and three “Top cited article” awards. She is Editor-in-Chief of “Advances in Sample Preparation” (Elsevier), Specialty Chief Editor of “Environmental Analysis” for Frontiers in Analytical Science (Frontiers), Associate Editor of the “Journal of Separation Science” (Wiley). Elia Psillakis is also Head of the Sample Preparation Study Group and Network of the European Chemical Society-Division of Analytical Chemistry (EuChemS-DAC), an elected member of EuChemS-DAC and an Affiliate Member of the International Union of Pure and Applied Chemistry (IUPAC). From 2014-2016, she was the Deputy Rector of Academic Affairs and Research at the Technical University of Crete and has served twice as the Director of postgraduate studies.
