In some cases, analysts cannot access the fire scene in the first few hours due to the dangers involved in the situation and, as a consequence, phenomena such as weathering start. Ignitable liquid weathering is an evaporation process that results in an increase in the abundance of non-volatile compounds relative to volatile compounds, and this process changes the chemical composition. In the present work, the weathering of samples of gasoline at different times (from 0 h to a month) has been studied using an electronic nose (eNose). The influence of the volume used (40 \u00b5L and 80 \u00b5L) and the type of support (cork, wood, paper and cotton sheet) has been studied. Chemometric tools have been used with the aim of ascertaining the weathering time for which the developed method is capable of detecting the presence of gasoline. The eNose was able to discriminate samples of weathered gasoline. The support used for the samples did not seem to have an influence on the detection and the system.<\/jats:p>","DOI":"10.3390\/s18010139","type":"journal-article","created":{"date-parts":[[2018,1,8]],"date-time":"2018-01-08T04:21:21Z","timestamp":1515385281000},"page":"139","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Study of the Weathering Process of Gasoline by eNose"],"prefix":"10.3390","volume":"18","author":[{"given":"Mar\u00eda","family":"Alia\u00f1o-Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Sciences, IVAGRO, University of Cadiz, Puerto Real, Cadiz P.O.
