Parameters such as analysis temperature, sampling time and choice of SPME fibre coating were investigated and sampling preparation strategies explored, including headspace sampling in vials and in gas sampling bags. The repeatability of the method was evaluated. It was found that a 7 d accumulation time at room temperature, followed by sampling using a DVB/CAR/PDMS fibre, with a sampling time of 60 min at room temperature was a suitable strategy for the detection of VOC emissions from a wide range of historic plastic and rubber artefacts. For 20 mL vials, a sample size of 50 mg was found to be appropriate and grinding the samples improved the repeatability of the analysis and yielded higher levels of emissions. A non-destructive adaptation of the method that could be used directly on historic objects in a museum environment is also presented. The detected emissions improve understanding of ongoing degradation processes within historic plastic and rubber materials, in addition to providing information on material composition. date: 2015 date_type: published publisher: Elsevier official_url: http://dx.doi.org/10.1016/j.microc.2015.08.027 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1053111 doi: 10.1016/j.microc.2015.08.027 lyricists_name: Curran, Katherine lyricists_name: Strlic, Matija lyricists_id: KCURR06 lyricists_id: MSTRL90 actors_name: Curran, Katherine actors_id: KCURR06 actors_role: owner full_text_status: public publication: Microchemical Journal volume: 124 pagerange: 909-918 issn: 1095-9149 citation: Curran, K; Underhill, M; Gibson, LT; Strlic, M; (2015) The Development of a SPME-GC/MS Method for the Analysis of VOC Emissions from Historic Plastic and Rubber Materials.
