Short description of the course

This course – LC-MS Method Validation –  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 course is largely based on the recently published two-part tutorial review:

The course contains lectures, practical exercises and numerous tests for self-testing. In spite of being introductory, the course intends to offer sufficient knowledge and skills for carrying out validation for most of the common LC-MS analyses in routine laboratory environment. The real-life analysis situations for which there are either examples or self-tests are for example pesticide analyses in fruits and vegetables, perfluoroalkyl acids in water, antibiotics in blood serum, glyphosate and AMPA in surface water, etc. It is important to stress, that for successful validation experience (both in analytical chemistry as such and also specifically in validation) is crucial and this can be acquired only through practice.

Running as MOOC

This course will be offered as a MOOC (Massive Open Online Course) during Nov 26, 2019 – Feb 07, 2020 and you can register to the course here

The MOOC is run in the UT Moodle environment. You can have a preview of the MOOC in Moodle environment as a guest without registering. There (course introduction) you will find detailed information about course organization, graded tests, formation of the grade and awarding the certificate. Guest access also allows you to view the course contents in Moodle. As a guest you cannot read forums and take quizzes.

Required preliminary knowledge

Introductory level knowledge of analytical chemistry, as well as liquid chromatography and mass spectrometry is required. More advanced knowledge of analytical chemistry and introductory knowledge of mathematical statistics is an advantage.

Study outcomes

The participant who has successfully passed the course knows:

  • the main performance parameters of analytical methods, what they show and which of them are particularly important in different situations;
  • the main mathematical concepts and tools in method validation;
  • the main approaches for evaluation of the performance parameters in the case of LC-MS analysis.  

The participant who has successfully passed the course is able to:

  • decide what data are needed for evaluating the different method performance parameters, understand the meaning of the available data and decide whether the available data are suitable and sufficient;
  • select the validation approach and design the experiments for obtaining suitable data;
  • quantify the relevant performance parameters using the available data and assess whether the obtained values are realistic;
  • assess the fitness of the method for the intended purpose based on the values of the evaluated performance parameters.

Organization of the course material

The course is organized in 11 thematic sections, of which most are in turn split into smaller subsections. The following parts are found in the sections:

  1. The sections (and also many subsections) start with a brief introduction stating the main topic(s) and study outcomes of the section.
  2. The main topic of the respective section is explained in one or several short video lectures. The videos are by default streamed in high quality from the UT Video server, which needs quite good Internet connection. If you have slow Internet connection we recommend watching the videos from YouTube, using the links below video screens.
  3. The lecture(s) is(are) complemented by a textual part. The textual part is in most cases meant to complement, not substitute the lecture (although in some cases the contents of the lecture are also repeated in some extent). It rather gives additional explanations and addresses some additional topics that were not covered by the lecture.
  4. The learners are introduced to the logo software, which helps to carry out validation of chromatographic methods. Learners are encouraged to use ValChrom throughout the whole course.

  5. Most sections end with a self-test, which enables to assess the acquired knowledge and skills. The self-tests contain questions, as well as calculation problems. The self-tests are on one hand meant for the participants to monitor their progress. On the other hand, however, they also promote thinking and provide (by the feedback of the questions) additional knowledge about validation in different practical situations. So, the self-tests are an intrinsic component of the course and participants are strongly recommended to take all of them.

Self-testing

Throughout the course there are numerous self-tests for enabling the participant to test his/her knowledge and skills in specific topics. Each test is graded as a percentage (100% corresponding to correctly answering all questions and correctly solving all problems).

Feedback is given as:

Correct answer, correctly recognised and marked by the student.
Correct answer, not recognised and not marked by the student.
Incorrect answer, however, considered correct by the student.

Explanatory feedback is displayed when wrong answer is selected. All self-tests can be taken as many times as needed and the success of taking these tests will not influence the final grade. We recommend that you take all the tests and work with them until you achieve score 100% and only then move to next topic.

Terminology and definitions

At the end of the thematic section there is Glossary, which gives definitions and/or explanations of the terms used in the course. Wherever possible, the used terminology adheres to the one used in the Tutorial review on validation of liquid chromatography–mass spectrometry methods (Literature sources 1 and 2).

This course is part of the Excellence in Analytical Chemistry (https://www.analyticalchemistry.eu/Erasmus Mundus master’s programme, which offers education in all aspects of Analytical chemistry, including metrology in chemistry (measurement uncertainty, method validation, reference materials, etc), as well as economic and legal aspects of chemical analysis.

This course is run within the framework of the Estonian Center of Analytical Chemistry with the aim of offering easily accessible knowledge in analytical chemistry to labs and industries in Estonia and elsewhere.

This list of main literature references of this course is selective, not exhaustive. The references were selected on the basis of the following criteria: (a) widely used and cited; (b) useful under practical lab conditions (i.e. not too deeply scientific or theoretical) and (c) a fairly recent version is available. 

In addition, at the end of the course materials there is a more voluminous list of literature sources that are referred to in various parts of the course and are meant for users who are more deeply interested in specific topics. The references are referred to in the course via numbers in square brackets, e.g.: [ref 15].
