E-training: School of Quality for Test Laboratories



The credibility of measurement results and control of processes and costs are key for the successful and efficient operation of any laboratory. In order to apply the right and effective approaches in your laboratory to ensure appropriate quality of operation and results, we invite you to 10 online intensive training sessions.

What do you gain by attending the e-School on Quality for Testing Laboratories?

Practical knowledge as a process specialist in a (bio)chemical and physical test laboratory on:

  • ensuring traceability of measurement results,
  • validation or confirmation of a measurement procedure,
  • evaluating measurement uncertainty and analyzing it from the point of view of the client's requirements,
  • implementation of an internal quality control,
  • participation in interlaboratory comparisons,
  • effective management of processes in the laboratory,
  • accreditation, standardization, and measurement infrastructure,
  • ensuring the successful operation of the laboratory according to the requirements of ISO/IEC 17025.


1. Introduction to the e-School on Quality for Testing Laboratories, analytical (measurement) procedure, measurement traceability, and reference materials

The participants are introduced to the school and analytical (measurement) procedure and measurement traceability in chemistry and beyond.

Together, we will look for answers to the following using practical examples:

  • What is an analytical procedure?

  • Why is ensuring measurement traceability important?

  • How do we do it in chemistry, and how is this different in physical measurements?

  • Certified reference materials

  • Are we familiar with infrastructure (accreditation, standardisation, metrology)?

2. Validation, internal quality control (use of control charts) and interlaboratory comparisons

With the help of practical examples, the participants learn about approaches to validating analytical procedures, preparation and interpretation of control charts and the basics of interlaboratory comparisons.

Only properly validated analytical procedures can be used in the laboratory. The following questions will be addressed:

  • Why is the validation of analytical procedures necessary and important?

  • How shall we approach the validation of standard analytical procedures?

  • When is an analytical procedure developed in a laboratory suitable for use?

  • What requirements do clients have regarding the quality of analytical results?

  • What is the result of the validation of an analytical procedure?

Validated analytical procedures must be adequately controlled as part of regular internal quality control. For this purpose, we often use control charts with which we visually display and monitor performance of an analytical procedure. The data can also be used to evaluate measurement uncertainty. Together we will discuss answers to the following questions:

  • Which types of control charts are most often used?

  • How to prepare a control chart?

  • How to interpret and evaluate data in control charts?

  • How to use data from control charts for measurement uncertainty evaluation?

3. Measurement uncertainty and confirmation of project task titles

With the help of practical examples, the participants learn about approaches and ways of evaluating measurement uncertainty.

We guarantee the credibility and reliability of analytical results through appropriate evaluation of measurement uncertainty. The following questions will be addressed:

  • What are the key definitions and basic concepts?

  • Is measurement uncertainty part of a measurement result?

  • How to evaluate measurement uncertainty?

  • How to report measurement uncertainty?

  • When is the reliability of measurement results adequate?

  • Are our measurement results comparable to the results of other laboratories at home and abroad?

4. Exchange of good practices and presentation of project tasks

  • Presentation of project tasks.

  • Exchange of good practices.

  • Challenges – How to proceed?

Working method

The school is dominated by active methods of work. Study cases are discussed and analyzed. During individual sections and parts, the participants solve exercises based on examples from their practice, following the lecturer's instructions.

To participate in e-learning, you need a device with Internet access (computer, tablet, smartphone), a camera and a microphone.

Project work

E-training is individually tailored, as each participant determines the content of the project assignment from their field of work with the help of the lecturer at the beginning of the school. The project work is an added value to the laboratory and the organization in the form of a solution to an individual problem or challenge at your work. The participants present their projects on the final day.


E-training consists of four sections. Each section contains three consecutive workshops of three academic hours, except for the last section, which ends after the presentation of the final assignments. Throughout the course, the participants are required to complete a project assignment with the help of the lecturer's interactive support.


Nineta Hrastelj, is a Doctor of Chemical Sciences. She has many years of experience in analytical chemistry, chemometrics and metrology, both at home and abroad, in private and public accredited research laboratories. She has been engaged in introducing quality management systems to analytical laboratories in different roles, i.e. from accreditation and laboratory management. She is the editor of four books on this topic and author of numerous scientific, professional, and popular articles and chapters. Since 2011, she has been the General Secretary of the European Chemical Society (EuChemS).






You will receive a certificate of successful completion of the program upon finishing the training.

E-Training will take place in a live online e-classroom. Up to two days beforetraining registered participants will receive a link to the online training. Participants need a computer with a microphone and a camera, as well as access to a reliably functioning internet connection to participate in online training without interruption.
