MOOC: Instrumental analysis of cultural heritage objects

Course description

This online course focuses on the instrumental analysis of cultural heritage objects. The course gives an overview of the most widespread instrumental techniques – both destructive and non-destructive – such as IR and Raman spectroscopy, SEM-EDS, XRF and XRD, ICP-MS, GC-MS, LC-MS, HRMS, etc that are used for the analysis of cultural heritage materials.

As of now, the course is still in the process of completion. However, a number of videos, textual materials, self-tests, etc are already available and you are welcome to start using them. We are adding more materials on a regular basis.

Once finished, the course will provide the basic knowledge and key aspects of different analytical methods focusing on their capabilities for the chemical analysis of cultural heritage as well as archaeological objects and interpretation of the obtained results. The course contains video lectures, textual materials for more thorough reading and numerous tests for self-testing. An important part of the course are practical examples (videos) and useful tips connected with the analysis of cultural heritage materials.

Most of the study materials are freely available from this website without any access restrictions or need for registration and can be used by people who want to study independently and do not intend to follow the full course. Detailed copyright information is at the bottom of this page. Once the course materials will be finished there will be course periods (which require registration) with interaction possibilities with teachers and between participants (on the Moodle platform). During the course period registered participants will have access to the Moodle e-learning environment where they can discuss with each other via forums, have access to additional study materials, incl. case study videos, etc., and can take graded tests.

Course plan and organization

This 1 ECTS course is organized in 6 sections (weeks), of which some topics are in turn split into smaller subsections. The topics covered during these weeks are the following:

WEEK 1: Course introduction; Optical microscopy
WEEK 2: Vibrational spectroscopy: IR spectroscopy and Raman spectroscopy
WEEK 3: Elemental and X-Ray methods: SEM-EDS, XRF, XRD, and (LA)-ICP-MS
WEEK 4: Chromatography and Mass spectrometry: general aspects
WEEK 5: Chromatography and Mass spectrometry: in practice
WEEK 6: Multimethod analysis + case studies

Required preliminary knowledge

Introductory level knowledge of chemistry, cultural heritage, analytical chemistry and analysis methods is an advantage.

Study outcomes

The participant who has successfully passed the course knows:

the main properties of the materials relevant to the cultural heritage objects;
general theoretical background of different instrumental techniques;
what information can be obtained with different instrumental techniques and how to use several techniques in combination for extracting maximum amount of information;
the main principles of operation of the different instrumental techniques.

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

choose analytical method suitable for the given analysis task and object at hand;
interpret the data provided by different methods and extract the necessary information;
assess the reliability of the obtained results.
