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 […]

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 […]

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 […]

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 […]
Yesterday I submitted my proposal for becoming a Marie Sklodowska-Curie fellow. So if everything goes as hoped I will be collaborating with Prof. Christoph Schalley group in Free University of Berlin from the next schoolyear. My project there will be about supramolecular chemistry, more precisely on rotaxanes and molecular machines based on rotaxanes. It will introduce […]
Last week I had a change to visit a brand new Polli laboratory of the Estonian University of Life Sciences together with our student Elmo. The Polli lab is located in Southern-Estonia near Karksi-Nuia and surrounded by breathtaking landscape with hills and lakes. The Polli laboratory is unique in Estonia as it combines equipment suitable […]
