Measurement Uncertainty MOOC: 744 participants from 85 countries!

UT_Measurement_Uncertainty_MOOC_Participants_2016On Monday, March 28, 2016 the web course “Estimation of Measurement Uncertainty in Chemical Analysis” was launched the third time as a MOOC (Massive Online Open Course).

The popularity of the course is this year somewhat higher than it was in 2014 and 2015: 744 participants from 85 countries (ranging from Bahama to Vietnam and from Zambia to Canada) have registered! (in 2014: 270 participants, in 2015: 400+) Image on the left shows the countries where the participants come from. As in the previous years, the majority of participants are from analytical laboratories, once again demonstrating the continuing need for training in measurement uncertainty estimation in analytical chemistry.

The full course material is accessible from the web page https://sisu.ut.ee/measurement/uncertainty. Some developments and improvements have been made to the course material, in particular, some more self-tests ave been added. The course materials include videos, schemes, calculation files and numerous self-tests (among them also full-fledged measurement uncertainty calculation exercises). In order to pass the course the registered participants have to take six graded tests and get higher than 50% score. These tests are available to registered participants via the Moodle e-learning platform. Participants who successfully pass the course will get a certificate from the University of Tartu.

It is planned to run this course as MOOC again in Spring 2017.

Second day of the EACH Winter School 2016

EACH_Winter_School_2016_Dissolved_oxygen_intercomparisonThe second day of the EACH Winter school was full of excitement.
The key event of the second day was dissolved oxygen intercomparison between the student teams. The samples were water samples from the nearby lake Pühajärv. The student teams used optical oxygen sensors (based on luminescence), see the photo on the left. The seriousness of the intercomparison is underpinned by the independent reference values determined using the highly accurate primary Winkler titration procedure (developed by Irja Helm in her PhD thesis).

The results of the intercomparison will be summarized at the closing of the Winter school.

On the right you can see the group photo (Lake pühajärv is behind the trees) taken right after the lunch and followed by a spontaneous snow fight (photo on the left, below) where the “African team” (Ime and Olivier, in the centre) performed stunningly well in comparison to the Nordic snow fighters!

EACH_Winter_School_2016_Snow_Fight The consortium committee spent most of the day interviewing students and discussing (including negotiations with university officials about maximum possible numbers of students) for distributing students to study tracks. The day ended with the long-awaited announcement that it will be possible to grant every student the preferred study track!

Excellence in Analytical Chemistry Winter School 2016 successfully started!

EACH_Winter_School_2016_LectureToday, on Jan 25, 2016, the first Winter School of the EACH programme started in Pühajärve (Estonia). Altogether 24 students from 17 countries participate (besides EACH students, also some other international students from Tartu have been invited). Leading European analytical chemistry experts act as teachers and supervisors at the Winter School.

The Winter School offers a diverse set of activities to the participants. There are lectures on advanced analytical chemistry topics, tasks on data analysis and choosing analytical strategies. One of the sessions is specifically dedicated to employment opportunities of analytical chemists. The most ambitious part, a full-fledged in situ intercomparison measurement (between student teams) of dissolved oxygen concentration in lake water, will be carried out on the second day of the Winter School.

The intense working is counterbalanced by winter sports activities and relaxing in spa/swimming pool.

Full information about the Winter School activities is available at http://www.ut.ee/EACH/each-winter-school/

 

Metrology in chemistry in a nutshell

Random_and_Systematic_Effects_TimelineIn a recent edition of the premier journal devoted to quality and metrology in chemistry Accreditation and Quality Assurance Ivo Leito has attempted to express in very simple terms the essence of Metrology in Chemistry. In the article Accred. Qual. Assur. 2015, 20, 229–231 he arrived at three main recommendations:

1. Whenever possible, comparisons with reference values should be carried out. The reference values can be realized in different ways: Certified reference materials (CRMs), Laboratory reference materials (LRMs), Measurements with reference methods, etc.

2. Data on stable samples should be collected over long time periods (e.g. as the X chart), in order to evaluate as many sources of variability in the analysis method, as possible. The longer the time period, the more systematic effects will become random and thus easier to evaluate (more on this topic can be found in a recent review on bias).

3. “Do not stop there!”, meaning that the above mentioned activities should run in a lab on a continuous basis.

As a conclusion, it can be said that constant improvement is the key to reliable analytical results.

 

Collaboration between UT and the Balkan area in environmental analysis

IsoFood Hg Training_Draft Programme_2.11.2015_Page_1
During Nov 25-27, 2015 the training seminar “Quality assurance for Hg measurements in food and environmental samples” was held at the Jožef Stefan Institute in Ljubljana. Ivo Leito participated as a teacher and conducted discussion sessions Validation data (Reproducibility, recovery, etc) and their meaning, Measurement uncertainty and Traceability: what it is and how to demonstrate it?.

Ivo_Leito_teaching_metrology_in_chemistry_in_Ljubljana_Nov_2015The seminar was highly successful – there was in-depth discussion during each of the sessions and the discussions continued during coffee breaks. The measurement uncertainty session featured a full-fledged uncertainty estimation (contaminant determination by LC-MS), which the participants carried out themselves on laptop computers that they had brought with them.

It is expected that the collaboration between UT and Jožef Stefan Institute (and other research centres in the region) will continue and deepen.

ECAC (AKKI) on the Cooperation festival “Right time, right place” (“Õigel ajal õiges kohas”)

Analuutilise_Keemia_Kvaliteedi_Infrastruktuur_ENGOn Oct 14, 2015 Tallinn University of Technology and University of Tartu jointly organized the first cooperation festival “Right time, right place” (“Õigel ajal õiges kohas”), venue: Mektory innovation centre, Tallinn).

The festival aimed first of all at intensifying collaboration between Estonian industry and academia, but also between different research teams of the two universities. The interest in the event was so large that at some point pre-registration was stopped because of too many participants. The participant number who eventually participated in the event reached 430.

The analytical chemistry research group of UT was also present at the festival and promoted the ECAC distributed interdisciplinary research infrastructure. ECAC unites the competence and analytical capabilities of three prominent organizations in Estonia: University of Tartu, Tallinn University of Technology and the Estonian Environmental Research Centre and offers access to analytical instruments as well as services and collaboration both to academia and industry. Ivo Leito made a presentation about the analytical possibilities of ECAC that can be of interest to the Industry: Analüütilise Keemia Kvaliteedi Infrastruktuur (AKKI) (in Estonian).

In addition, we demonstrated our FT-IR analysis capability and had a fully operational ATR-FT-IR instrument with us (image on the right), enabling any interested person to run material analysis of either the samples that we brought with us or almost anything that could be found on site. People were very interested in the analysis of wood coatings, different polymers and also of their own clothes (e.g. for determining whether a necktie is made of silk or polyester) and research fellow Signe Vahur – our main FT-IR expert – was busy all the day to record and interpret spectra and give explanations to interested people.

This possibility of instant ATR-FT-IR analysis proved to be the most popular topic in the Chemistry thematic room of the festival and attracted much attention from people with very different backgrounds. This is not surprising – this instrumental method has been in the core of a number of research collaboration projects with industry in the past and is expected to be so also in the future.

EACH and AMS students strongly benefit from the expertise and instrumentation that has been accumulated by ECAC (AKKI). Several of the EACH/AMS teachers are directly involved in ECAC and a number of ECAC’s instruments are used in teaching and thesis work.

 

Using MOOCs for teaching analytical chemistry: experience at University of Tartu at the Euroanalysis 2015

Leito_Measurement_Uncertainty_MOOC_Euroanalysis_2015On Sept 07, 2015 Ivo Leito gave a presentation Using MOOCs for teaching analytical chemistry: experience at University of Tartu at the Euroanalysis XVIII (Bordeaux, France).

The presentation outlined the contents and organisation of the material in the on-line course Estimation of measurement uncertainty in chemical analysis, the ways of using it (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 in spring 2014 and 2015. 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.
