Maalide ja polükroomsete objektide juures kasutatavate materjalide koostise teadmine on oluline kunstiajaloo (selgitada välja materjali kasutus) ja konserveerimise (kasutada autentseid materjale) seisukohalt. Projekti eesmärk on töötada välja metoodika ajalooliste objektide värvikihtide kvantitatiivse koostise (pigmentide, täiteainete, sideaine identsus ja sisaldus koos määramatuse hindamisega) määramiseks, kasutades kombineeritult erinevaid instrumentaalmeetodeid (ATR-FT-IR, Raman, SEM-EDS, (LA)ICP-MS ja CHNS elementanalüüs, toetavateks meetoditeks GC-MS, MALDI-FT-MS, ESI-ja APCI-FT-MS) ja kemomeetrilisi meetodeid (PCA, PLS, jne). Põhihüpotees: Maali või polükroomse objekti värviproovi koostist saab kvantitatiivsel (mõistliku täpsusega) määrata kasutades kombineeritult erinevaid üksteist täiendavaid analüüsitehnikaid, kui on olemas piisav arv sobivaid kalibreerimisproove ja samuti sobivad kemomeetrilised mudelid.
The knowledge of the composition of the materials used in paintings and polychrome objects is important for art history (elucidating the materials usage artwork assignment) and for conservation (to use authentic materials). The objective of the project is developing a methodology for elucidating the quantitative composition (identity and contents of pigments, fillers, binder, together with uncertainty estimates) of paint layers of historic objects using a combination of techniques (ATR-FT-IR, Raman, SEM-EDS, (LA)ICP-MS and CHNS elemental analysis, supported by GC-MS, MALDI-FT-MS, ESI-and APCI-FT-MS) and chemometric tools (PCA, PLS, etc). The main hypothesis: The composition of a sample of a painting (or a polychrome object) can be determined with useful accuracy using a combination of a diverse set of instrumental techniques when a sufficient number of suitable calibration samples, as well as suitable chemometric models are available.
