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 […]

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 […]
