European Mass Spectrometry Conference 2018

Last week I had a chance to take part in the European Mass Spectrometry Conference that was hosted by DGMS (German Society for Mass Spectrometry) and SFSM (Frence Society for Mass Spectrometry). Below I share a few key ideas from this nice conference that took place in Saarbrücken over 5 days. The conference was opened […]

p-value that we call statistically significant

In this post I am going to talk about p-value. You can either watch the illustrative video or read my thoughts below. Enjoy!  This week p-value made it to the Science news feed. The whole story started already in the middle of last year, when Bejamine and coworkers published in Nature Human Behaviuor a […]

What can we learn from mass spectrometry about charged droplets?

Charged droplets occur everywhere in the world. They are created by the oceans (known as see spray aerosols), near waterfalls and in thunderstorm clouds. Such droplets are expected to play significant role in environmental processes. Similar droplets are also created in electrospray ionization (ESI) source. Mari Ojakivi joined our group three years ago to conduct […]


Last week there were two awesome analytical chemistry events in Tel Aviv. On Monday 23th of January there was an international workshop on validation of test methods, human errors and measurement uncertainty of results organized by Dr. Ilya Kuselman. In this event I had an amazing chance to present my experiences in the validation in […]

Defences in our group: Asko Laaniste and Hanno Evard

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. […]

Recognition of Piia and Jaanus on scientific works competition

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 […]

Sporty chemists

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 […]
