24. Norske Symposium i Kromatografi was a great success

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 […]

Jaanus Liigand received first prize on the Estonian National Contest for University Students for his doctoral thesis

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 […]

Towards safe up- and re-cycling of textile waste

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 […]

What is non-targeted analysis and why it should go quantitative?

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 […]

Solutions and Workflows in (Environmental) Molecular Screening and Analysis (SWEMSA) conference

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 […]

17th Nordic Mass Spectrometry Conference in Espoo

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, […]

We are happy to introduce: Dr. Piia Liigand and Dr. Jaanus Liigand

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 […]

Prof. Susan D. Richardson Emerging Contaminants: State of the Art and New Discoveries

We are happy to invite you to the lecture by Prof. Susan D. Richardson on the topic of “Emerging Contaminants: State of the Art and New Discoveries” taking place on the 14th of August 2019. Follow the event on Facebook. Emerging Contaminants Environmental research continues to expand beyond traditional, regulated contaminants to emerging contaminants, such as […]

Ionization efficiency of an oligopeptide can be predicted based on its amino acid composition

Ionization efficiency of oligopeptides does depend on the chemical composition of the peptide. Longer oligopeptides generally obey higher ionization efficiency; however, for peptides containing more than seven amino acid the ionization efficiency values are relatively similar. Also, the ionization efficiency values of the amino acids can be used to estimate the ionization efficiency of a […]
