Built your open-source 2LabsToGo system 2.-7.09.2024

The latest system (we will publish soon) has an integrated autosampler, a nebulizer, mini-incubator, UV/Vis/FLD/bioluminescence detection including reflectance and backlight illumination and many further improvements. In advance, we will order (latest bill of materials, payment by installments possible upon request) and 3D print all parts for you. This means you can directly start at the workshop to mount yourself your system, whereby we will guide you. Some reading: Non-target screening of complex samples for hazards.

Remark: Already in 2011, I repeatedly asked the manufacturers of HPTLC devices to get involved in this project and collaborate to develop a low-cost small-scale system, but they refused and replied that I could do it myself. We did so during the last decade. In the late phase, funding of a PhD position was thankfully obtained via the Bundesamt für Ausrüstung, Informationstechnik und Nutzung der Bundeswehr grant E/U2AD/KA018/IF565.


Open-source means useable for everybody!

Visit the 2LabsToGo at Analytica in Munich, 9-12 April 2024

  • 1,066 exhibitors from 42 countries, around 34,000 visitors from 117 countries
  • New record number of participants at the analytica conference
  • In focus: digitalization and sustainability in the laboratory of the future

Full days at Analytica2024: Three times a day the 1-h Live Lab presentation/moderation (0:26) and an oral presentation every day (Forum, Conference, DGF), a poster presentation and two interviews. Happily, I met my former guest researcher Hanna Nikolaichuk. I asked her if she could present the 2LabsToGo at the Live Lab during my two parallel morning lectures. Of the 12 Live Lab presentations, your two presentations were definitely the coolest! Many, many thanks to Hanna!!!

Great interest in our research

I got a call from Guido Deußing saying proudly Thank you because his interview with me in the journal Laborpraxis attracted the most interest by far in 2023 and has done so for years: Genotoxische Verbindungen sicher und effizient in Nahrungsmitteln bestimmen - Gesund ungesund: Erbgutschädigende Pflanzenöle?, Laborpraxis 7-8 (2023) 48-51


February 2024: Join our course on planar bioassays

Learn how hyphenated HPTLC can make a difference, and join our next hybrid online course on effect-directed analysis taking place in February/March 2024The better your (bio)analytical tool, the more you understand. Free of costs for students and members of other universities.

Some reading: Non-target screening of complex samples for hazards

34. Doktorandenseminar

Erfolgreich wurde unsere Forschung auf dem 34. Doktorandenseminar des Arbeitskreises Separation Science vom 8.-10.01.2024 in Hohenroda, Hessen vertreten. Isabel Müller präsentierte "On-surface Untersuchung der Verdauung von Kohlenhydraten und Fetten unter Verwendung von Mund- und Darmenzymen" und Max Haumann "Genotox-Screening von MOSH/MOAH in Schokolade". Sie haben es beide sehr souverän gemeistert - Gratulation!



Selected as journal front cover

Thank you for the honor to select our graphical abstract figure as journal front cover (click on cover to increase it)!

Cover image: Tomato products were screened with a ten-dimensional hyphenation with integrated simulated gastrointestinal digestion. Non-digested and digested samples were compared side by side. In their effect-directed profiles, 14 bioactive compounds from classes of lipids, plant hormones, spices, and pesticides were identified. The innovative hyphenation allowed for a non-target proactive food safety analysis. (From: Schreiner, T., Eggerstorfer, N.M. & Morlock, G.E.

All the best for 2024!

Wenn's alte Jahr erfolgreich war, dann freue dich aufs neue.
Und war es schlecht, ja dann erst recht.
Albert Einstein eben Einstein!
Kann nicht jeder Tag, sogar jeder Gedanke, ein neuer Anfang zum Guten sein?

Unter den großen Persönlichkeiten, die an der JLU geforscht, gelehrt und studiert haben, befindet sich nicht Einstein, aber Justus Liebig, Wilhelm Conrad Röntgen (Nobelpreis für Physik 1901), Wangari Maathai (Friedensnobelpreis 2004), Volker Bouffier, Frank-Walter Steinmeier und viele mehr.

HPTLC development for cheers with sparkling wine...
