“…When cases are opened, VOC concentration decreases. However, after 24 h the VOCs concentration is again sufficiently high to be detected by SPME-GC-MS [18,19]. The selection of the sampling points was based on the visual observation of crystals made by the museum conservators and collection manager in a first exploratory phase.…”

“…Other VOCs released by the case materials such as acetic acid, benzene derivatives, oximes, aldehydes, and alcohols were also identified by SPME-GC-MS. The presence of these substances in the museum environment can initiate undesirable reactions causing damage to the collection [7,18,29,30]. The monitoring of these compounds will be investigated in a later phase of the project, which will focus on developing mitigation strategies to reduce the VOCs accumulated in the cases.…”

“…The selection of the locations was based on the presence or absence of visible signs of efflorescence on objects observed during previous on-site condition surveys. SPME fibers were placed inside the cases for 24 h. A recent publication has shown a good compromise between sensitivity and prolonged exposure times of SPME fibers, allowing the accumulation of sufficient analyte onto the fiber within a reasonable timeframe [18,19]. However, it should be emphasized that long exposure times can create fluctuations on the extraction yield of the analytes.…”

“…Identifying the potential sources of all VOCs detected in the exhibition cases can pose an arduous task and was not the primary goal of this study. For example, acetic acid detected in all sampling points can be either emitted by the construction materials analyzed in the previous section or by the objects [18,31,32]. The presence of aldehydes can be associated to the degradation of textiles or cellulosic materials [33].…”

“…The detection of naphthalene, especially in the cases containing organic objects, may be due to its historic use as pesticide during the twentieth century in many museum collections [34]. Alkylbenzene derivatives are known to be commonly present in the atmosphere and are considered indoor pollutants [18].…”

Two mass spectrometry (MS) methods, solid-phase microextraction gas chromatography (SPME–GC–MS) and direct analysis in real time (DART-MS), have been explored to investigate widespread efflorescence observed on exhibited objects at the Smithsonian’s National Museum of the American Indian in New York (NMAI-NY). Both methods show great potential, in terms of speed of analysis and level of information, for identifying the organic component of the efflorescence as 2,2,6,6-tetramethyl-4-piperidinol (TMP-ol) emitted by the structural adhesive (Terostat MS 937) used for exhibit case construction. The utility of DART-MS was proven by detecting the presence of TMP-ol in construction materials in a fraction of the time and effort required for SPME–GC–MS analysis. In parallel, an unobtrusive SPME sampling strategy was used to detect volatile organic compounds (VOCs) accumulated in the exhibition cases. This sampling technique can be performed by collections and conservation staff at the museum and shipped to an off-site laboratory for analysis. This broadens the accessibility of MS techniques to museums without access to instrumentation or in-house analysis capabilities.
