The 9th Workshop and Meeting of the Users’ Group for Mass Spectrometry and Chromatography (MaSC ) for the study of cultural heritage objects took place on June 3-7, 2019 in Ottawa, the capital of Canada. One of our group members – PhD fellow Eliise Tammekivi – also participated in the workshop and gave an oral presentation at the meeting.
Practical instructions for the analysis of dyes, resins and volatile organic compounds (VOCs)
The workshop of MaSC 2019 took place in the Canadian Conservation Institute (CCI) and Parks Canada, where the Thermal Separation Probe (TSP) was presented as a novel device for thermal desorption and „slow pyrolysis“ analyses in gas chromatography-mass spectrometry (GCMS) by the leading researchers in the study of cultural heritage materials. With the instructions from Jennifer Poulin (CCI) the participants were able to conduct the analysis of dyes and identify natural resins by the help of AMDIS software. With instructor Dr. Gregory D. Smith (Indianapolis Museum of Art at Newfields) participants could perform evolved gas analysis of museum exhibition materials once again with TSP and GCMS.
Topics from fish oil in paintings to the interpretation of highly complex GCMS data
The Meeting of MaSC 2019 took place in the National Gallery of Canada. Presentations were given by the world’s leading analysts about the GCMS analysis of art and historical artifacts. For example, Kate Fulcher (British Museum) talked about the complications of identifying black liquids applied to ancient Egyptian coffins and Corina Rogge (The Museum of Fine Arts Houston) about the utilization of fish oil containing house paints to artists’ paintings in economically difficult times. Additionally, Michael Schilling and Henk van Keulen presented the wonderful advantages of using AMDIS software and ESCAPE for the identification of compounds in complex and small cultural heritage samples. Also, it was Eliise’s first full talk at an international conference, where she presented our groups’ work on the topic „Quantitative analysis of binders in cultural heritage objects“. Specifically, she presented the comparison of four common derivatization procedures in the field of cultural heritage for the quantitative GCMS analysis of oils. For the opportunity to attend the workshop and meeting she would like to thank the organizers of MaSC 2019 and Dora Pluss scholarship (Archimedes).
