As a result of a recent development in our group, it is now, for the first time, possible to rigorously measure acidity of acids in biphasic systems (aqueous phase at equilibrium with a water-immiscible phase) by using biphasic pKa values…
This week is the first study week for the new students of Applied Measurement Science (AMS) and EACH Erasmus Mundus Joint Programme (EACH). Altogether 17 (2 AMS and 15 EACH) students started their studies. The countries of origin of the students are very…
On May 13, 2021, the online course (MOOC) Estimation of measurement uncertainty in chemical analysis offered by the University of Tartu finished successfully. Eventually, altogether 950 people registered from 97 countries. 501 participants actually started the course (i.e. tried at…
On Apr 29, 2021 the webinar “Mobile Phase pH in Liquid Chromatography” took place. Altogether 101 people participated from 41 countries, ranging from Portugal to Philippines and from Peru to Nepal. It is well known that in liquid chromatography, mobile…
This year the Estonian Research Council has presented 49 female Estonian scientists to the AcademiaNet database. From the Unversity of Tartu, seven names were given, including Dr Signe Vahur (on the picture), a research fellow in our Chair of Analytical…
It is well known that in liquid chromatography, mobile phase pH is an important parameter, significantly affecting the retention of acidic and basic analytes. Yet, mobile phase pH is tricky to measure because mobile phases are usually aqueous-organic mixtures and…
On Tuesday, March 23, 2021, the web course Estimation of Measurement Uncertainty in Chemical Analysis was launched for the eighth time as a MOOC (Massive Online Open Course)! Currently, 925 participants from 97 countries are registered – the largest audience…
A highly interdisciplinary study ranging from computational chemistry to cultural heritage has now been published – Experimental and Computational Study of Aminoacridines as MALDI(-)-MS Matrix Materials for the Analysis of Complex Samples, J. Am. Soc. Mass Spectrom. 2021. 9-aminoacridine (9-AA)…
The equilibrium acidity scale (pKa scale) in acetonitrile (MeCN) has been supplemented by numerous new compounds and new ΔpKa measurements and has been published in Eur. J. Org. Chem. 2021, 1407–1419 (Open access). The pKa scale now contains altogether 231 acids…
The 2021 edition of the web course (MOOC) Estimation of Measurement Uncertainty in Chemical Analysis will be running from March 23 to May 4, 2021. Registration is now open! The full course material (as well as the registration link) is…
Altogether 791 people were registered from 86 countries. 338 participants actually started the course (i.e. tried at least one graded test at least once) and out of them 221 successfully completed the course. The overall completion rate was 28%. The…
On the 3rd of September, 2020, EACH master students successfully defended their master’s theses! The topics of the theses demonstrated the wide scope of the field of EACH studies. They ranged from the application of near-infrared (NIR) spectroscopy to liquid…
On the 8th of June, 2020, eight EACH master students successfully defended their master’s theses via the web. The defenders and the members of the committee were caught on a screenshot. Defenders: Varun Vashneel Sharma, Hark Karkee, Larissa Silva Maciel,…
