The method for the characterization of volatile organic compound (VOC) emission profiles from hot mix asphalt (HMA) consisted of a two-step procedure: the analytes, initially adsorbed into the coating in no vacuum- or vacuum-assistance mode, were then analyzed following an automated thermal desorption (TD) step. We took advantage of the theoretical formulation to reach some conclusions on the relationship between the physical characteristics of the monolithic material and uptake rates. A total of 35 odor-active volatile compounds, determined by gas chromatography-mass spectrometry\/olfactometry analysis, contributed as key odor compounds for HMA, consisting mainly of aldehydes, alcohols, and ketones. Chemometric analysis revealed that MonoTrapTM RGC18-TD was the better coating in terms of peak area and equilibrium time. A comparison of performance showed that Vac\/no-Vac ratios increased, about an order of magnitude, as the boiling point of target analytes increased. The innovative hybrid adsorbent of silica and graphite carbon monolith technology, having a large surface area bonded with octadecylsilane, showed effective adsorption capability, especially to polar compounds.<\/jats:p>","DOI":"10.3390\/molecules29204943","type":"journal-article","created":{"date-parts":[[2024,10,21]],"date-time":"2024-10-21T09:58:24Z","timestamp":1729504704000},"page":"4943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Vacuum-Assisted MonoTrapTM Extraction for Volatile Organic Compounds (VOCs) Profiling from Hot Mix Asphalt"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3078-7188","authenticated-orcid":false,"given":"Stefano","family":"Dugheri","sequence":"first","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5623-1671","authenticated-orcid":false,"given":"Giovanni","family":"Cappelli","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niccol\u00f2","family":"Fanfani","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8665-845X","authenticated-orcid":false,"given":"Donato","family":"Squillaci","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Rapi","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3804-9607","authenticated-orcid":false,"given":"Lorenzo","family":"Venturini","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9190-6550","authenticated-orcid":false,"given":"Chiara","family":"Vita","sequence":"additional","affiliation":[{"name":"PIN\u2014University Center \u201cCitt\u00e0 di Prato\u201d Educational and Scientific Service, University of Florence, 59100 Prato, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8310-5240","authenticated-orcid":false,"given":"Riccardo","family":"Gori","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Florence, 50139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piero","family":"Sirini","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Florence, 50139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2693-8633","authenticated-orcid":false,"given":"Domenico","family":"Cipriano","sequence":"additional","affiliation":[{"name":"Ricerca sul Sistema Energetico (RSE), 20134 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mieczyslaw","family":"Sajewicz","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, University of Silesia, 40006 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0579-1035","authenticated-orcid":false,"given":"Nicola","family":"Mucci","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Polvara, E., Roveda, L., Invernizzi, M., Capelli, L., and Sironi, S.
