These parameters have been optimized taking into account the presence of matrix signals, in order to avoid the interference of these peaks in acrylamide determination. The best separations were achieved using a microemulsion consisting of 0.8% m\/v <jats:italic>n<\/jats:italic>\u2010amyl alcohol, 3.3% m\/v sodium dodecyl sulfate (SDS), 6.6% m\/v 1\u2010butanol, and 89.3% m\/v 40\u00a0m<jats:sc>M<\/jats:sc> phosphate buffer at pH 6.5 working at 15 kV in uncoated silica capillaries. Linear calibration curves over the range studied (1.25\u2013125\u00a0\u03bcg\u00b7mL<jats:sup>\u20101<\/jats:sup>), the detection limit (0.70\u00a0\u03bcg\u00b7mL<jats:sup>\u20101<\/jats:sup>), and both run\u2010to\u2010run (up to 3.4% for concentration and 1.6% for time values) and day\u2010to\u2010day precision (lower than 11.6% for concentration) have been established. Finally, the applicability of the MEEKC method developed has been demonstrated by analyzing levels of acrylamide present in samples of home\u2010made French fries.<\/jats:p>","DOI":"10.1002\/elps.200406044","type":"journal-article","created":{"date-parts":[[2004,10,7]],"date-time":"2004-10-07T14:05:14Z","timestamp":1097157914000},"page":"3257-3262","source":"Crossref","is-referenced-by-count":29,"title":["Microemulsion electrokinetic chromatography for the analysis of acrylamide in food"],"prefix":"10.1002","volume":"25","author":[{"given":"Elisabet","family":"Bermudo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Ruiz\u2010Calero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lluis","family":"Puignou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria T.","family":"Galceran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,7]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1246\/cl.1991.391"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200305637"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(99)00350-7"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)00088-1"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200390041"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)00791-3"},{"key":"e_1_2_1_8_2","first-page":"435","volume":"60","year":"1994","journal-title":"International Agency for Research on Cancer (IARC)"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/jf020302f"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1039\/b204938d"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/1438-9312(200211)104:11<762::AID-EJLT762>3.0.CO;2-R"},{"key":"e_1_2_1_12_2","first-page":"638","volume":"93","author":"Biedermann M.","year":"2002","journal-title":"Mitt.
