Recently my first single-authored paper became public. It concerns the solvent effect on electrospray ionization efficiency and matrix effect. As we have talked about ionization efficiency and its solvent effects also previously, let’s focus on matrix effects this time. As LC/ESI/MS is the tool for various fields in routine analyses (quality control over pesticides but also mycotoxins in the food we eat, drug monitoring […]

We are happily back from IMSC in Toronto and a very important celebration in our group has occurred! On the last day of August two PhD theses were defended in our group by Asko Laaniste and Hanno Evard. Asko wrote his thesis on ionization sources. Specifically focusing on the comparison of different sources for pesticides. […]

A small part of our group is going to International Mass Spectrometry Conference from 20th to 26th of August in Toront and present the latest results of our studies. The results are so hot that these are not yet available in the journals: M-T-053 pH effects on electrospray ionization efficiency Jaanus Liigand W-T-019 Ionization efficiency […]

Today the importance of environmental analyses has been generally accepted. However conventional environmental monitoring programs are somewhat limited in scope as these programs only search for compounds that have been previously found to exist in contaminated samples. These compounds make up only a fraction of compounds that may be present in target samples overall. In […]

Already in last spring when we were writing the tutorial review on LC/MS method validation, Ivo introduced us the idea of making a MOOC (massive open online course) on the same topic. By that time he had launched the first MOOC of our institute that has had hundreds of students so far, on such complex […]

In a recent semester, I have been involved in several training activities. The most important of these have been the training day for water analyses laboratories organized by EKUK and the practical aspects of working in the laboratory by TÜ Katsekoda. My lecture/seminar in the first training was about sample matrices as the source of […]

This week two of my students have been recognized by different organizations for their outstanding scientific work. Jaanus Liigand received first prize in the field of natural science for his Masters thesis “Electrospray ionisation efficiency scales: mobile phase effects and transferability” on a scientific works competition by Estonian Research Council. Also our (the theses were […]

In a bit less than a year an international conference EcoBalt will be held in Tartu. The conference will last for 4 days 9.-12.October 2016. This is the first time EcoBalt will be held in Estonia, though it has taken place in Baltics for more than 15 years now. The conference is organized by University […]

Yesterday for the first time I saw a catalogue of a famous company producing and selling cooking accessories. And I soon become puzzled. A lot of people fancy these products lately, however everything they produce is made out of plastic. My family and some of my closest friends are well aware that I have never […]

Most certainly the event of the week has been the Tartu city marathon and more precisely the competition between labs held during this marathon. Our students organized a competition “which lab has the highest participation rate on the city marathon”. The “event” for our institute actually started even a lot earlier as several people not […]
