GDME is a simple, inexpensive, and environmentally friendly technique that allows the simultaneous extraction and derivatization with 2,4-dinitrophenylhydrazine (DNPH) of selected volatiles. The extraction conditions were optimized using design of experiments through a 24 full fractional design followed by a Box\u2013Behnken design, resulting in 35 min of extraction at 45 \u00b0C using 500 \u00b5L of DNPH 0.15%. The analysis of commercial MDF samples with different characteristics, such as thickness or colour, showed a distinct emission profile of volatile carbonyls. The principal emitting compounds found were formaldehyde, acetaldehyde, acetone, butanal, pentanal, hexanal, heptanal, octanal, and nonanal. A total of 25 compounds were identified using MS, including saturated and unsaturated aldehydes, ketones, dicarbonyls, and benzaldehyde-derivatives. This method can be a valuable tool for the qualitative evaluation of VOCs released from wood-based panels and for the assessment of indoor-air quality.<\/jats:p>","DOI":"10.3390\/separations11040092","type":"journal-article","created":{"date-parts":[[2024,3,25]],"date-time":"2024-03-25T14:00:23Z","timestamp":1711375223000},"page":"92","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Volatile Carbonyl Compounds Emission in Dry-Process Fibreboard: Identification through a Selective GDME-HPLC-DAD-MS\/MS Method"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6220-4955","authenticated-orcid":false,"given":"F\u00e1tima Daniela","family":"Gon\u00e7alves","sequence":"first","affiliation":[{"name":"LAQV-REQUIMTE\u2014Departamento de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias da Universidade do Porto, Rua do Campo Alegre, s\/n, 4169-007 Porto, Portugal"}]},{"given":"Jorge M.","family":"Martins","sequence":"additional","affiliation":[{"name":"DEMad\u2014Departamento de Engenharia de Madeiras, Instituto Polit\u00e9cnico de Viseu, Campus Polit\u00e9cnico de Repeses, 3504-510 Viseu, Portugal"},{"name":"LEPABE\u2014Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"},{"name":"AliCE\u2014Associate Laboratory in Chemical Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4557-7113","authenticated-orcid":false,"given":"Lu\u00edsa H.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"DEMad\u2014Departamento de Engenharia de Madeiras, Instituto Polit\u00e9cnico de Viseu, Campus Polit\u00e9cnico de Repeses, 3504-510 Viseu, Portugal"},{"name":"LEPABE\u2014Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"},{"name":"AliCE\u2014Associate Laboratory in Chemical Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"given":"Jos\u00e9 Ant\u00f3nio","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE\u2014Departamento de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias da Universidade do Porto, Rua do Campo Alegre, s\/n, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0313-6985","authenticated-orcid":false,"given":"Rui Miguel","family":"Ramos","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE\u2014Departamento de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias da Universidade do Porto, Rua do Campo Alegre, s\/n, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,25]]},"reference":[{"key":"ref_1","unstructured":"Irle, M., Barbu, M.C., Niemz, P., Carvalho, L., Martins, J.M.S., Costa, C.A.V., Muszynski, L., Launey, M.E., Dunky, M., and Aderhold, J.
