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 […]
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 […]
Students I supervised last school year gave me a rafting trip as a present with them for my birthday in May and on this Friday we went to Võhandu river for this trip. Altogether we passed 20 km containing both quite slow flow parts but also some cascades. Slow parts, though not that adventures, taught […]
Today I would like to introduce you to two books that I find very valuable and that can be freely downloaded from the internet. The “Five keys to successful LC methods” and “Controlling selectivity in reversed-phase LC” are collections of articles published in LC/GC in the section “LC Troubleshooting” by John W. Dolan. It’s useful […]
In my statistics course, similarly to I guess all other teachers concerned in calibration, I teach that for instrumental analyses weighted linear regression should be used. Why? Non-weighted linear regression (the one we can use with LINEST, SLOPE and INTERCEPT in excel) assumes same signal precision (repeatability standard deviation in other words) for all concentrations […]
