Apart from trivalent chromium (Cr(III)), which is used for tanning, leather often contains hexavalent chromium (Cr(VI)), resulting from the oxidation of Cr(III) during the tanning process. This study deals with the chromium compounds in simulated sweat when brought into contact with Cr(III) or Cr(VI) and with chromium\u2010tanned leathers. A capillary electrophoresis (CE) method was developed, with inductively coupled plasma\u2010sector field\u2010mass spectrometry (ICP\u2010SF\u2010MS) for element\u2010specific detection. Two different electrophoretic runs, applying once the positive and once the negative polarity mode, were necessary for the detection of positively and negatively charged chromium species. Although sometimes described in the literature, a pre\u2010run derivatization of the chromium\u2010species was not performed here to prevent species transformation. 50\u00a0mmol\u00b7L<jats:sup>\u22121<\/jats:sup> sodium phosphate at a pH of 2.5 was used as CE separation buffer and as make\u2010up liquid for the CE\u2010ICP\u2010SF\u2010MS interface. When applied to simulated sweat samples incubated with Cr(VI), this method showed that methionine is responsible for the reduction of Cr(VI) into Cr(III), which, at its turn, forms a complex with lactic acid. In the case of sweat plus Cr(III), the latter step was also seen. Applied to simulated sweat in contact with leather samples, the method developed showed the presence of the former species among a much more complex pattern.<\/jats:p>","DOI":"10.1002\/elps.200410221","type":"journal-article","created":{"date-parts":[[2005,3,30]],"date-time":"2005-03-30T10:16:58Z","timestamp":1112177818000},"page":"1703-1711","source":"Crossref","is-referenced-by-count":30,"title":["Capillary electrophoresis hyphenated to inductively coupled plasma\u2010sector field\u2010mass spectrometry for the detection of chromium species after incubation of chromium in simulated sweat"],"prefix":"10.1002","volume":"26","author":[{"given":"Veerle","family":"Van Lierde","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cyrille C.","family":"Ch\u00e9ry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luc","family":"Moens","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Vanhaecke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,4,26]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0536.1996.tb02295.x"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0536.2002.470301.x"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0536.1997.tb00211.x"},{"key":"e_1_2_1_5_2","first-page":"4","volume":"48","author":"Geier J.","year":"2000","journal-title":"Dermatol.
