Measurement_Uncertainty_MOOC_Successfully_FinishedOn May 14, 2018 the on-line course (MOOC) Estimation of measurement uncertainty in chemical analysis offered by University of Tartu finished successfully.
Eventually altogether 521 people registered (270 in 2014, 489 in 2015, 757 in 2016, 363 in 2017) from 76 countries (a number of participants joined after the start of the course). 358 participants actually started the course (i.e. tried at least one graded test at least once) and out of them 218 successfully completed the course (141 in 2014, 169 in 2015, 308 in 2016, 148 in 2017). The overall completion rate was 42% (52% in 2014, 34% in 2015, 40% in 2016, 41% in 2017). The completion rate of participants who started the studies was 61% (67% in 2014, 60% in 2015, 67% in 2016, 68% in 2017). The completion rates are nicely consistent over the last years and can be considered very good for a MOOC, especially one that has quite difficult calculation exercises, which need to be done correctly for completing the course.

The participants were very active and asked lots of questions. The questions were often very much to the point and addressed things that are really important to analysts in their everyday work. The course has several forums (general and by topic) and the overall number of posts to them during the course period reached almost 300 (!) (overall number of posts, both from participants and from teachers) and the forums are still active and posts are still coming in.

This active participation made teaching of this MOOC a great experience also for us, the teachers. The discussion threads gave a lot of added value to the course and some of them triggered making important modifications to the course materials, even during the course.

We want to thank all participants for helping to make this course a success!

We plan to repeat this course again in Spring 2019.

 

AKKI infopäev 03.05.18 AKKI_Infopaev_030518äratas ootuspäraselt laialdast huvi ja õnnestus suurepäraselt! Osalejaid oli 57, mis oli ligilähedane maksimaalsele oodatud osalejate arvule. Osalejad olid tõeliselt mitmekesiste taustadega – tööstuste esindajatest süvateadlasteni, laboritöötajatest riigiametnikeni. Oli nii professoreid kui doktorante, laborijuhataid kui omakäelisi analüütikuid.

Ettekannetega olid esindatud AKKI kolm partnerit, samuti ka mõned organisatsioonid, kes on AKKI laboritega edukalt koostööd teinud – Eesti Kunstiakadeemia (koostöö Europa Nostra auhinna pälvinud Rode altari projekti raames) ja OÜ Holz Prof (koostöö tootearenduse raames). Päeva huvitavaim osa oli kahtlemata ringkäik Chemicum’i laborites ja vabas vormis diskussioonid AKKI spetsialistidega.

Osalejatega vesteldes jäi kõlama üldine seisukoht, et selline teadmisi ja aparatuuri koondav ettevõtmine, mida AKKI endast kujutab, on kogu Eesti jaoks väga vajalik. Vestluste käigus tekkisid ka mitmed konkreetsed koostööideed, mille realiseerimine algab lähiajal.

&nbbsp;

AKKI meeskonnal on rõõm teatada, et on toimumas esimene AKKI võrgustikku tutvustav infopäev.

Ürituse raames on võimalik saada ülevaade AKKI partnerite tegevustest ning koostöövõimalustest. Lisaks on võimalus uudistada ringi Chemicumis ning suhelda meie teadlastega.

Üritus toimub Tartus ja on eesti keeles.

Every year Estonian University of Life Sciences organises a conference called “Healthy animal and healthy food” where Dr. Riin Rebane made a presentation “Fight against food fraud” which explained the ever-expanding role of analytical chemists in food science. Reasons for food fraud vary, but are almost always for monetary gain and therefore food fraud is in constant progress. One good example is honey analysis, where for decades there has been a change in methods in order to identify whether honey is real or whether it is identified with correct botanical or geographical origin. As a natural product, no two honeys are identical and this makes identification further more challenging for the chemists. One of the possible methods is amino acid analysis since the amino acid content can be like a fingerprint for honeys and in University of Tartu we have analysed few hundreds of Estonian honeys and have seen that that foreign honeys do differ in most cases and also that there is a correlation between the amino acid content and botanical origin. But nevertheless, even this method might not work every time and chemists are looking towards methods such as nuclear magnetic resonance spectroscopy and even DNA-analysis to get better certainty for determining the origin of honey.

The summary based on the presentation was also reported in the newspaper Maaleht.

 

U_MOOC_Countries_of_Participants_2018On Tuesday, March 27, 2018 the web course Estimation of Measurement Uncertainty in Chemical Analysis was launched the fifth time as a MOOC (Massive Online Open Course)!

Currently more than 450 participants from 70 countries are registered! As was the case in the previous years, the majority of participants are from analytical laboratories. This once again demonstrates the continuing need for training in measurement uncertainty estimation for practicing analytical chemists.

The full course material is accessible from the web page https://sisu.ut.ee/measurement/uncertainty. As is usual, some developments and improvements have been made to the course material. in particular, the description of course organisatsion was improved; more explanations and examples were added on random and systematic effects within short and long term; the typical requirements for determining repeatability and within-lab reproducibility have been clearly outlined; more explanations on the main principles of modifying a model in a modelling approach have been given, together with an example. Some changes are still in the pipeline.

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 pass six graded tests and get higher than 50% score from each of tehm. These tests are available to registered participants via the Moodle e-learning platform.

LC_MS_Validation_MOOC_Participants_Countries_2017On Tuesday, November 28, 2017 the web course LC-MS Method Validation was launched for the second time as a MOOC (Massive Online Open Course). There are 423 registered participants (by more than 100 more than in 2016) from 71 countries, ranging from Bolivia to Indonesia and from Sweden to Tanzania. Image on the left shows the countries where the participants come from.

This is a practice-oriented on-line course on validation of analytical methods, specifically using LC-MS as technique. The course introduces the main concepts and mathematical apparatus of validation, covers the most important method performance parameters and ways of estimating them. The LC-MS validation course is delivered by a team of 8 teachers, each with their own specific area of competence. This way it is expected to offer the best possible knowledge in all the different subtopics of analytical method validation.

The full set of course materials is accessible from the web page https://sisu.ut.ee/lcms_method_validation/. The course materials include videos, schemes, calculation files and numerous self-tests (among them also full-fledged calculation exercises). In order to pass the course the registered participants have to take all tests and get higher than 50% score from each of them. 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 autumn 2018.

Anu_Teearu_Kristjan_HaavThis is the range of topics addressed on Aug 16, 2017 as PhD dissertations addressing these topics were defended at UT Institute of Chemistry.

 

Anu_Teearu_presenting_her_PhD_ThesisAnu Teearu (left on the photo) in her thesis titled Development of MALDI-FT-ICR-MS methodology for the analysis of resinous materials addressed the analysis of resinous materials in order to obtain the maximum amount of high-accuracy data from these complex materials. Several important methodological developments (novel calibrants, novel matrix materials, etc) were introduced to MALDI-FT-ICR-MS and its capabilities were assessed during the analysis of three case study samples originating from different types of cultural heritage objects.

 

Kristja_Haav_presenting_his_PhD_ThesisThe central aim of the thesis of Kristjan Haav Quantitative relative equilibrium constants measurements in supramolecular chemistry was development of highly accurate binding constant measurement methods. The key development was measuring relative equilibrium constants instead of absolute ones, which enables eliminating or strongly reducing the influence on several error sources. Kristjan tested the applicability of this approach on two instrumental techniques: UV-vis spectrophotometry and nuclear magnetic resonance spectrometry (NMR). Comparison of the two – completely independent – techniques showed good agreement between the obtained results and thus supports the reliability of both of them.

Kristjan Haav is an alumnus of the Applied Measurement Science programme.

Leito_LCMS_Validation_EuroMS_2017On 21.06.17 Ivo Leito gave a talk titled Review on validation of liquid chromatography–mass spectrometry methods at the Euro Mass Spectrometry 2017 meeting (London, UK). The talk focused on the two-part Tutorial review on validation of liquid chromatography–mass spectrometry (LC-MS) methods

as well as on the related on-line course (MOOC) LC-MS Method Validation and the ValChrom validation software.

The reception of this talk was one of the warmest during the meeting! Several participants came later to say words of thank for offering such a valuable resource to the LC-MS community. There were also some interesting ideas proposed regarding topics that could be covered in the online course. LC-MS and MiC issues, such as validation, are among core competences of the UT Analytical Chemistry research group. The tutorial review, the on-line course, as well as the ValChrom software together form a nice outcome of joining these competences together.

Concerning the topics of the meeting in general, they were remarkably diverse and not so heavily dominated by biomedical MS as is often the case at mass spectrometry meetings. Interesting presentations were given on gas-phase ion processes, different laser techniques in MS (e.g. for analysis of solids without sample preparation), advanced catalysis studies by MS, LC-ICP-DRC-MS for trace element speciation, the possibility of making a high-end LC-HRMS system an “open access” system within an organization, etc.
