By using commonly applied planar chromatographic systems and \u03bcPADs devices, stationary phases (silica and cellulose based), different solvent mixtures (methanol\u2013water and dichloromethane\u2013methanol), and proportions varying from 0 to 100% (v\/v), micro-TLC migration profiles of several dyes described in terms of characteristic of chromatographic parameters (retardation factor, peak base width, and asymmetry factor) were investigated. Combining these results with some quantum mechanics calculated properties for each solute (dipole moment, polarizability), and by using the data mining approach, we modeled this overall chromatographic behavior in order to describe experimental data. With this approach, we were able to predict with reasonable confidence some chromatographic properties. This effort its crucial in order to (1) optimize solute elution, (2) increase mixture resolution, and (3) identify some molecular properties of analytes for designing simple micro-TLC. It is hoped that the presented nonhypothesis-driven data-mining approach can be helpful for understanding the chromatographic behavior of dyes on silica and cellulose adsorbents using the simplest mobile phases. This should be helpful for further designing the micro-TLC separation systems or \u03bcPADs quantification devices based on cellulose and related biopolymers and considering dye compounds as analytes for separation and sensing molecules.<\/jats:p>","DOI":"10.5740\/jaoacint.18-0061","type":"journal-article","created":{"date-parts":[[2018,5,4]],"date-time":"2018-05-04T01:18:16Z","timestamp":1525396696000},"page":"1437-1447","source":"Crossref","is-referenced-by-count":8,"title":["Toward the Understanding of Micro-TLC Behavior of Various Dyes on Silica and Cellulose Stationary Phases Using A Data Mining Approach"],"prefix":"10.1093","volume":"101","author":[{"given":"Jorge C","family":"Pereira","sequence":"first","affiliation":[{"name":"University of Coimbra, Centro de Qu\u00edmica de Coimbra, Department of Chemistry, 3004-535 Coimbra, Portugal"}]},{"given":"Jorge M C","family":"Marques","sequence":"additional","affiliation":[{"name":"University of Coimbra, Centro de Qu\u00edmica de Coimbra, Department of Chemistry, 3004-535 Coimbra, Portugal"}]},{"given":"El\u017cbieta","family":"W\u0142odarczyk","sequence":"additional","affiliation":[{"name":"Koszalin University of Technology, Faculty of Civil Engineering, Environmental and Geodetic Sciences, Department of Environmental Technologies and Bioanalytics, \u015aniadeckich 2, 75-453 Koszalin, Poland"}]},{"given":"Bo\u017cena","family":"Fenert","sequence":"additional","affiliation":[{"name":"Koszalin University of Technology, Faculty of Civil Engineering, Environmental and Geodetic Sciences, Department of Environmental Technologies and Bioanalytics, \u015aniadeckich 2, 75-453 Koszalin, Poland"}]},{"given":"Pawe\u0142 K","family":"Zarzycki","sequence":"additional","affiliation":[{"name":"Koszalin University of Technology, Faculty of Civil Engineering, Environmental and Geodetic Sciences, Department of Environmental Technologies and Bioanalytics, \u015aniadeckich 2, 75-453 Koszalin, Poland"}]}],"member":"286","published-online":{"date-parts":[[2019,11,23]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/5\/1437\/32426847\/jaoac1437.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/5\/1437\/32426847\/jaoac1437.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:18:42Z","timestamp":1584641922000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/101\/5\/1437-1447\/5654057"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2019,11,23]]},"published-print":{"date-parts":[[2018,9,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.18-0061","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2018,9,1]]},"published":{"date-parts":[[2018,9,1]]}}}
