JustTLC concluded to be the most sensitive analysis software

In a research study on image analysis software for the detection and quantitative evaluation of fluorescent compounds, JustTLC was concluded to be the most sensitive of all tested software. It was also seen that JustTLC showed very good linearity (r > 0.9952), high precision and accuracy.

"I am very glad that JustTLC achieved such good evaluation result in comparison with the other analytical TLC software on the market. We are committed to deliver the best image analysis results in combination with the best user experience and this tells us that we are doing exactly that", says Gustav Träff, founder of Sweday.

Four different image analysis software packages were applied and compared by the research team at the Faculty of Chemistry and Chemical Engineering, Babeş-Bolyai University in Romania. In their publication "A Comparative Study Concerning The Image Analysis in Thin Layer Chromatography of Fluorescent Compounds" they give a detailed and thorough examination of the software. The image analysis methods were developed and validated for the simultaneous determination of quercetin and kaempferol in food supplements. The chromatographic separation used Silica gel 60 TLC plates as the stationary phase and carbon tetrachloride:acetone:formic acid (35:11:3, v/v/v) as the mobile phase. The plate images were recorded by a digital camera and imported in the image analysis software. The final results were validated by evaluating the linearity, precision, and accuracy of the methods used to quantify synthetic and real samples.

Third JustTLC publication within a year

A paper using JustTLC was recently accepted for publication in the journal 'Carbohydrate Research'. It is the third publication within a year based on the work done by a research group at the Center for Organic Chemistry in Lund, Sweden.

“This work would never have been completed without JustTLC. We have increased our project throughput and allowed our self to try new things that we didn’t have time to do before. This project is a perfect example of why we employ JustTLC. It was partly done by a group of students that did the bulk measuring using JustTLC. The simple structure and ease of use made it possible for the students to do real science and not just a tailored experiment. I only wrapped it up after their great contribution,” says Richard Johnsson, one of the scientists behind the publication.

“We constantly see new possibilities with JustTLC and this is another strong example of how JustTLC can support good sciences. Not only did this research group find new clues about reductive openings of benzylidene acetals, they also engaged several students while doing it. Students will someday become the next key scientists discovering the nature of our world. If they get interested we all have a lot to gain”, says Gustav Träff, founder of Sweday.

Sweday exhibits JustTLC at the Organic Days 2008 Conference

At the 21st Organic Days 2008 Cconference, Sweday presented a poster and did a live demonstration of JustTLC in combination with an ordinary office scanner.

The poster was published together with the Center for Organic Chemistry in Lund, Sweden. It displayed findings based on two previously published articles and two different example setups for quantitative TLC analysis. During the conference a live presentation of JustTLC in combination with an ordinary office scanner was conducted. The demonstration showed how simple, intuitive and reliable quantitative compound analysis can be achieved in minutes rather than days if you use e.g. a HPLC setup.

“People were amazed by the simplicity and ease of use that the live demonstration with JustTLC showed. We brought all required equipment in a hand luggage sized suitcase and rigged it in less than five minutes. In yet another five minutes our first quantitative TLC analysis experiment was demonstrated and completed in front of the audience. I am almost amazed myself on how smoothly it all works”, says Gustav Träff, founder of Sweday.

“The response at the conference was a complete success and it encourages us to continue our revolutionary work on quantitative TLC analysis. Why stop your TLC analytics when you are merely minutes away from a quantitative method that just works?”, Gustav Träff concludes.

The Organic Days Conference (Organikerdagarna in Swedish) is the largest conference on organic chemistry in Sweden. It is an annual event where all major research laboratories meet during a three day session to lecture on their latest findings. This year it was held 9-12 June in Åhus, Sweden.

New findings on acetals achieved by using JustTLC

The largest research unit for chemistry in Scandinavia, the Center for Organic Chemistry in Lund, Sweden, has published new findings on acetals based on experiments conducted with JustTLC. Acetals are important molecules both in nature and during e.g. organic synthesis.

“The experiments that lead to the published findings were not even possible to think of before we had JustTLC. Now, we can test new ideas at a much lower cost and higher throughput. It is easier, less error prone, more simple and straightforward to do quantitative compound analysis. We have done this research at twice the normal speed. This is a fundamental improvement when you do science like we do”, says Ulf Ellervik, associate Professor at The Center for Chemistry in Lund, Sweden.

“Yet again the power of JustTLC has been shown in a real world application. JustTLC is now becoming the obvious choice even at the most sophisticated and modern research lab. The laboratory that performed the acetal experiments was completely remade and upgraded during 2006. JustTLC integrated seamlessly and became a central part of the top modern arsenal in no time. We can only conclude that JustTLC reveals the true power of TLC analysis”, says Gustav Träff, founder of Sweday.
