UT analytical chemistry education activities at CroLab “Laboratory Competence 2016″ Conference

Leito_CroLab_2016On Oct 20, 2016 Ivo Leito gave presentation titled Education Activities in Metrology in Chemistry in Vinkovci (Croatia) at the conference Laboratory Competence 2016 organized by CroLab – the Croatian Association of Laboratories.

The presentation contains information about the Applied Measurement Science and Excellence in Analytical Chemistry master’s programmes et University of Tartu, about the international consortium Measurement Science in Chemistry, about the on-line course Estimation of Measurement Uncertainty in Chemical Analysis and the new on-line course LC/MS Method Validation. Also the recently published tutorial reviews were touched upon.

The presentation led to a number of new contacts and invitation to next events. Participants were impressed by the breadth of activities as well as by the very strong team working on these things at UT. In addition, Ivo Leito was interviewed by the Croatian national television.


EcoBalt 2016 Successfully finished!

EcoBalt_2016_Group_PhotoOn Wednesday 12.10.16 the EcoBalt 2016 conference – first time organized in Tartu, Estonia – finished successfully! 42 oral talks and 43 posters were offered to the more than 150 participants from more than 25 countries. The conference featured two tutorial sessions – on measurement uncertainty and on validation of LC/MS analytical methods. The mesmerizing introductory multimedia presentation by Sven Zacek about Estonian nature and the stunning closure talk about “impossible things” by Meelika Hirmo from Let’s Do It! World were certainly among the highlights of the conference.

A number of AMS and EACH students participated in the conference.

We thank all the participants for making EcoBalt 2016 a success!

eesti-keskkonnauuringute-keskus_riidekoti_kujundusIn few hours the EcoBalt 2016 conference will start, for the first time in Tartu!

The EcoBalt conference series has traditions dating back to 1993 and has been envisaged from the beginning as a Baltic event. Nevertheless, this is the first time that it takes place in Estonia (previously only in Latvia and Lithuania).

We are very glad to welcome more than 160 registered participants from more than 25 countries, making it a truly international conference! The nearby countries are represented as well as e.g. Philippines, Mexico, India, China, Nepal, Sri Lanka, … A number of EACH students also participate in EcoBalt 2016!

The EcoBalt 2016 programme is very diverse: topics ranging from ultramodern environmental analytical techniques to environmental management and from nanoparticles in environment to global climate change.

EcoBalt 2016 is organised jointly by UT in collaboration with TTU and Estonian Environmental Research Centre in the framework of the ECAC consortium.


EuCheMS 2016: MOOCs in teaching analytical chemistry at University of Tartu

mooc_vs_traditional_courses_in_chemistryOn Sept 13, 2016 Ivo Leito gave a presentation Using MOOCs for teaching analytical chemistry: experience at University of Tartu at the EuCheMS 2016 Congress (Seville, Spain).

The presentation outlined the contents and organisation of the material in the on-line course Estimation of measurement uncertainty in chemical analysis, the different ways of using the on-line material (for independent learning, for self-testing, as an information source and as a basis for running as a MOOC) and the experience of running it as a MOOC (Massive Open Online Course) at University of Tartu during the three MOOC editions in 2014 to 2016. An important part of the presentation was devoted to analyzing the pros and cons of MOOCs as a way of teaching and in particular as a way of teaching analytical chemistry (or its subdisciplines). It was concluded that MOOCs do have advantages, especially if compared to short training courses for practitioners. The talk created quite some interest and discussions after the session.

Detailed discussion of this topic has been published: I. Leito, I. Helm, L. Jalukse. Anal Bioanal Chem 2015, 407, 1277–1281.
The course material is available for all interested people from https://sisu.ut.ee/measurement/

Preparation of a new MOOC course Validation of LC-MS analysis methods is currently underway by the group of analytical chemistry. The materials of the LC-MS validation course are nearing completion and are already available online.

New EACH and AMS students started their studies!

EACH_and_AMS_Students_UT_2016This week was the first study week for the new Applied Measurement Science students and EACH Erasmus Mundus. Altogether 19 students started their studies. The countries of origin of the students are Vietnam, Philippines, Russia, Serbia, Kazakhstan, China, Sri Lanka, Nepal, Nigeria, Mexico, Lithuania, Tunisia, Pakistan and Greece. During the introductory meeting an overview of the programme was given (see the slides) and a large number of questions were asked and answered, accompanied by tea/coffee and cake.

We wish successful studies to all new students!


What is the best LC-MS ion source? How to determine Limit of detection of a method?

Asko_Laaniste_Hanno_EvardThese very important (and up to now not completely solved) questions got a lot clearer on Aug 31, 2016 as PhD dissertations addressing these topics were defended at UT Institute of Chemistry.

Asko Laaniste (left on the photo) in his thesis titled Comparison and optimisation of novel mass spectrometry ionisation sources has carried out an extensive experimental comparison of 4 different LC-MS ion sources operated altogether in 7 different modes in the analysis of 41 different pesticides. The obtained large pool of data was used for comparing the sources in terms of matrix effects, limit of detection (LoD), repeatability, linearity, signal to noise ratio (S/N) and sensitivity.

Asko demonstrated that for low levels of analytes in most cases the conventional ESI is the ion source of choice (provided the analytes are ionizable with ESI), while dopant-assisted APPI is a good alternative if low detection limits are not required and if compounds not ionizable with ESI are determined.

This is currently the most comprehensive comparison of this type available and Asko’s thesis (and the forthcoming publication) could serve as a “desk manual“ for LC-MS practitioners on choosing ion source for LC-MS analysis.

The central question of Hanno Evard’s thesis Estimating limit of detection for mass spectrometric analysis methods was: what is the best way of evaluating detection limit (LoD) of an analytical method? There are around ten widespread approaches for LoD in the literature (plus less well known ones) and the LoD values obtained using different approaches can differ by up to 10 times.

Hanno (right on the photo) carried out comprehensive analysis of the literature approaches and combined that with extensive experiments. As a result he was able to propose and convincingly justify one approach, which has merits over others and should be used for evaluation of LoD.

A two-part tutorial review on this topic is in press with the Analytica Chimica Acta journal and we expect that it will be for analytical chemists the definitive source on LoD estimation for years to come.

Hanno Evard is an alumnus of the Applied Measurement Science programme – the predecessor programme of EACH.

Our warmest congratulations to Asko and Hanno!

EcoBalt 2016: the programme is converging nicely!

LogoWe are glad to announce that the EcoBalt 2016 programme has been converging nicely – we have now a lot of interesting presenters! At the same time there are still free slots so that we continue to accept abstracts both for oral and poster presentations. The conference takes place in Tartu (Estonia) during 9.-12. October 2016.

In addition to the scientific content the EcoBalt 2016 conference will be hosting two tutorial classes with the following topics:

— Tutorial on measurement uncertainty (Oct 09, 2016)
— Tutorial on LC/MS method validation (Oct 12, 2016)

Both of these will be interactive sessions oriented towards solving practical questions, making decisions in measurement uncertainty and validation, performing calculations, etc. The tutorials assume basic knowledge of the topics – measurement uncertainty and validation, respectively. There is no extra fee for the tutorial classes – the conference fee covers also the tutorials. If you are interested in participation in one or both tutorial classes, please register to the EcoBalt 2016 conference.

The registration is still open at the EcoBalt 2016 website.

The most current information is in the EcoBalt 2016 4th circular.

We also have created the EcoBalt 2016 Facebook page where all the latest news are presented.

If any questions, do not hesitate to contact the local organizers, Dr Riin Rebane (riin.rebane@ut.ee) or Prof Ivo Leito (ivo.leito@ut.ee).

EcoBalt 2016 is an environmental science conference, with a strong focus on environmental analytical chemistry and metrology/quality aspects of analytical measurements and there will be a special session there dedicated to these topics.

MSC Summer School 2016 successfully finished!

EACH_Students_at_MSC_Summer_School_2016On Friday 22.07.2016 The MSC Euromaster Summer School 2016 finished. The feedback from some of the UT participants indicates that it was again a success! They shared their experience:


TetianaTetiana Melnyk (Ukraine):
I want to say a big big thank you for the opportunity to go to summer school! It was a great experience, and I met a lot of new people. If you ask me to evaluate, I would say it was excellent!

SantoshSantosh Raman Acharya (Nepal):
Summer school was amazing experience for me. The most challenging and exciting part was to work with people from all over the world with different experience in their respective fields. We made a lot of presentations, lab works and audit practice in the company “Umicore”, and the most inspiring moment was to meet with Sander Sannik at the summer school. In overall it was a full package of learning with fun!

AleksandraAleksandra Lelevic (Montenegro):
I have to say that I don’t remember when I had so much fun and when I have been so tired all at the same time :-)! It was a very intensive course that brought together a very interesting group of people and I am very happy I got the opportunity to meet closely many of them. I particularly liked the practical part of the school where we had to carry out analysis ourselves and work out a way to get along and think of good solutions together as a group.

RabinRabin Neupane (Nepal):
Summer school was a perfect platform where I got challenges as a Analytical Chemist and develop an ability to cope with those challenges. I must thank Ivo for the lectures in Meteorology in Chemistry at UT, which was foundation for me to be confident and perform well in summer school. Besides lectures in summer school, I would miss the bar, friends from different corners of world, those dances and karaoke we had at end of each day in summer school. It has been a life time experience. Thank you Ivo for such an opportunity.


The 2017 MSC Summer school will take place in Lithuania.
