Disruptive thinking

Analytical results are the basis on which we make calculations and decisions, perform risk assessments, give recommendations, and identify problems. But what if our analytical tools aren’t efficient enough to protect us?

PhD defense no. 2

We may have 5-6 PhD defenses this year. As the second PhD student, Tamara Schreiner defended her cummulative dissertation on Non-target screening of emerging bioactive and hazardous compounds in complex matrices via multi-hyphenated techniques with summa cum laude in March!

The developed 8D to 12D hyphenated non-target screening strategies proved to be an excellent analytical tool for the characterization of new bioactive compounds from complex samples. The more information can be obtained in an analysis, the more accurately an unknown bioactive compound (= most important among the thousands of compounds present in a complex sample) can be characterized. The newly developed multidimensional workflows are applicable in both routine and research settings. They substantially complement current food analysis and are likely to significantly advance food safety and improve consumer safety.

Food chemistry laboratory module

Practical block course on food analysis limited to 40 students in March...

Find out what these powders are?

Are the saccharides labelled properly in the different types of chocolate?

... and so on.... some impressions.... how to deal with titration...

...even on one's knees to measure properly... 

...or diagonal stand if it may help for fatty acid methyl ester formation after Soxhlet extraction of peanut flips.

Which cereal starch is it? Sometimes not so easy.... but no severe battles observed so far.

Find out which is the emulsion type of the food formulation!

Beautiful natural anthocyanines and pH dependency of the colorization

Quantification done via photometry if you do not have HPTLC....

Sure, we have HPTLC.... here a snapshot taken in 2011 when I started in Gießen. It was the 13th course!

Sensory modules

Semester-free period can be very busy: We had to handle four modules in March, whereof two were the sensory modules. We performed the two blocked courses for the 7th time (before it was integrated as part in other modules), but always a new adventure.... now, we have to become vegan... to fulfill the emerging needs of the world....


The different trays were prepared 125 times each to be collected by the students!

When prepared, the whole team formed an "automatic delivery belt" and proved that humans work much better than machines.

Guidance to the lecture hall with last minute aroma swabs put on the tray to start directly with the odour test.  

Finally, in the lecture hall, concentration was very high on making the right decisions, which we discussed.

Guests on earth

Very sad and unexpected, as I always had the feeling that such a strong woman will stay on earth forever.... We lose an active and extremely productive scientist in our midst, a highly treasured companion in our world of science. Intellectually always on the move, she was a hardworking and dedicated "chromatographer" whose heart beat for planar chromatography. She was a very good female role model in the scientific community. Teresa was not only active in the Department of General Chemistry and Chromatography at the University of Silesia in Katowice, Poland, but has also been one of the founders of the annual chromatographic symposium since 1977. She (co-)organized 42(!) symposia for Chromatographic Methods of Investigating the Organic Compounds in Katowice and surrounding areas with great dedication. She had a warm, hands-on, motherly nature and a winning smile, often garnished with a touch of a nice irony and winking eye. She always had an opinion or point of view. Discussions with her were entertaining and never long enough, and scientifically, she always made a constructive contribution. It is a great honor to have known her and to have her in our midst, although she left us too early, aged 76. We will remember her very fondly. She will remain in our hearts (and thus on earth) forever.


TLC Book

Again our CHROMarts about anthycyane and lactose-free dairy product analyses on the cover of the newest TLC book of Colin Poole. We were asked to contribute with two book chapters, which we wrote with pleasure!

2014, 1st ed.           2023, 2nd ed.


PhD defense no. 1

The new year comes with joy: mid of January, Stefanie Kruse has brilliantly defended her cummulative dissertation Development and comparison of standardized bacterial metabolite profiles by hyphenated planar chromatography for characterization of feed additives and probiotic feeds, which was evaluated as summa cum laude!

The quantification of added probiotics (very specific bacterial strain) in the complex animal feed matrix has succeeded via specific/selective metabolites! She found the needle in the haystack. The better the analytics, the more we understand relationships and gain new knowledge and insights. It is therefore important to constantly reconsider prevailing analytical strategies or to develop new strategies.

Gleich durchstarten! Kaum ausgekatert (Silvester), schon kommt der erste Vortrag 2LabsToGo - HPTLC für alle nach nicht einmal einem Jahr Promotionsforschung auf dem 33. Doktorandenseminar des Arbeitskreises Separation Science vom 8.-10.1.2023 im Hessen Hotelpark Hohenroda. Kevin Jakob hat es prima gemeistert! Join us in 2024!


More than 1100 scientific contributions give HPTLC a voice

We study the power of hyphenated HPTLC, independently in a non-profit way, as it is our fundamental task as a scientist and researcher at academia. We solve severe challenges and provide advise. Our vision is to produce edge science taking the metro! HPTLC is a highly sustainable separation technique, too. Nothing new, but more in the trend now.

  • More than 100 guest researchers from over 27 countries joined our group
  • About 25 doctorial students trained in HPTLC
  • 1600 multiplicator students a year 
  • Over 100 projects with other academic groups and industries

All the best for 2023!

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.
