Recently we have published a paper on advancement in predicting ionization efficiency in ESI and using this for estimating the concentration of pesticides in cereal samples without the need for analytical standards. In this paper, we explored the possibility to use machine learning for fast and accurate prediction of ionization efficiency. Previously we have carefully […]

Last week the 17th MassSpec forum took place in Vienna with two days full of exciting mass spec talks. The conference was open by Prof. Dr. Kevin Pagel who introduced the work of his group that has focussed on revealing the structure of sugar molecules in the gas phase. His group has made great use […]

After the move to Stockholm University, my group is looking for new members. Currently, we have available a post-doc position. If you enjoy coding, are interested in machine learning and applying these tools to solve problems in mass spectrometry and you hold a PhD or are graduating soon, this is your chance! For more information […]

From 5th until 7th or January, I was happy to participate at the 24th Norwegian Symposium on Chromatography as an invited speaker. It was a very good and successful start for the new science year: three days filled with exciting talks on emerging chromatography techniques and detection methods. Some of the most talks that I […]
Last week Dr. Jaanus Liigand received the first prize on the Estonian National Contest for University Students for his doctoral thesis Standard substance-free quantification for LC/ESI/MS analysis based on the predicted ionization efficiencies. During his PhD studies, Jaanus investigated quantitatively the factors affecting the ionization efficiency of compounds in electrospray ionization. For that ionization efficiencies for […]

The textile industry is one of the most polluting industries, at the same time, only 1% of the material is recycled. This causes not only a loss of valuable resources but also environmental impact through landfills. One of the main obstacles in textile recycling and upcycling is the quality of the source material. The quality of the […]
In June at HPLC conference I had a super nice possibility to explain what is non-targeted screening and why it should be developed into a quantitative method. Now, this video is available for all of you. I thank a lot Alasdair Matheson from LC&GC, who invited me to do the video, LCGC video teem, and HPLC […]

At the end of October, a three-day SWEMSA conference on non-targeted analysis took place in the Erding, close to Munich, Germany. On the conference representatives from different non-targeted communities came together to present the last progress made in the field. The focus was very strongly on the data analysis side but also method development and […]

This week the 17th Nordic Mass Spectrometry conference was held in Espoo, Finland. With around 150 participants form nordic countries, the conference covered various different topics within the field of mass spectrometry. I presented some of the most recent results from our group in the field of quantitative suspect screening for pesticides and mycotoxins. Also, […]

Last week two of our PhD students, Piia Liigand and Jaanus Liigand, successfully defended their PhD theses. Both Piia and Jaanus worked intensively and successfully on understanding the ionization process in electrospray ionization source (ESI) and applying this knowledge for quantifying compounds with LC/ESI/MS without standard substances. Congratulations to the fresh doctors! Piia is continuing […]
