In the recent years, we have made significant progress in ionization efficiency studies. In our previous publications, we have shown that our approach can be applied in both electrospray positive and negative mode (we have recently also enabled comparing the logIE values measured in both ESI modes numerically), that our approach is transferable between different […]

I am Mari, currently finished a second-year as a master’s student in Kruve Lab. I spent the last semester (Spring 2018) in Greensboro, North-Carolina as an exchange Graduate student in Chemistry. Besides taking classes like every other exchange student, I could also do some fascinating research in Dr Cech Lab. I have always wanted to […]

Our PhD student Jaanus is currently doing research in the group of Prof. Edwin De Pauw at the University of Liege in Belgium he had a nice opportunity to take part in a 21st annual meeting of Belgian Society for Mass Spectrometry that was held on 29th of March in Liege. The meeting was organized […]

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 […]

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 […]

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 […]

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. […]
