Behind glass display cases and inside archive shelves, museum collections \u2013 from historical cellulose acetate films to vintage vehicles \u2013 are continuously exposed to invisible volatile organic compounds (VOCs) and corrosive gases. Harmful airborne pollutants, such as acetic acid, formaldehyde, nitrogen dioxide, and hydrogen sulfide, can cause irreversible damage, including metal corrosion, pigment alteration, and material embrittlement.<\/p>\n\n\n\n

To safeguard cultural heritage, researchers in the Conservation Science Department at the Deutsches Museum are advancing innovative air-monitoring techniques as part of the EU-funded Horizon Europe SIMIACCI project. Initial investigations using passive sampling devices, such as Magic Chemisorbers and Radiello\u00ae, were carried out in collaboration with ARPAV (Regional Agency for Environmental Protection and Prevention of Veneto, Italy) to identify suitable case studies.<\/p>\n\n\n\n

In parallel, the team has developed an analytical method based on thermal desorption\u2013gas chromatography\u2013mass spectrometry (TD-GC\/MS) for the quantitative determination of acetic acid, which is not reliably detected by the currently used gas monitoring system. Using specialized multibed sorbent tubes, the method allows concentrations between 75 and 1500 ppb to be measured in a single analysis. Methods for detecting additional pollutants are planned as the next steps in the project.<\/p>\n\n\n\n

The developed method is already revealing risks in real-world museum environments. In the Deutsches Museum’s film archive, TD-GC\/MS measurements detected acetic acid concentrations exceeding 1500 ppb \u2013 more than three times the recommended upper threshold of 402 ppb. The monitoring approach is also being applied in storage areas housing a historic Trabant P601 automobile and in a display case in the Robotics exhibition.<\/p>\n\n\n\n

<\/a>Looking ahead, these high-precision TD-GC\/MS measurements will serve two key purposes within the SIMIACCI project: to compare with the measurements of the real-time indoor air quality (IAQ) sensors in order to validate their accuracy and to evaluate the performance of novel metal-organic framework (MOF) sorbents designed to capture airborne contaminants. The combination of advanced chemical analysis with smart environmental monitoring will support the development of a prediction model to forecast the pollutants evolution that shall provide early warnings and suggest maintenance actions.<\/p>\n\n\n\n

<\/a>From July to November 2026, researchers from the Conservation Science Department also presented the first project results at several local, national, and international public events and conferences.<\/p>\n\n\n\n
