Pigment analysis

Pigment analysis, using Raman spectroscopy. The analysis was carried out at the Ångström Laboratory, Uppsala University. A series of in-depth articles on the Raman results is underway and will soon be published in a scientific journal. The full report will be available on the website in April 2024. The main author of the report is Dr. Lars Helldahl.
