The on\u2010line interface was a modification of a split\u2010flow interface typically used for coupling flow systems to CE. The modification consists of an additional channel closed with a septum that permits the introduction of the fiber in the interface, right at the inlet region of the separation capillary. The interface was designed to be used with commercial fibers. Although commercial fibers can be used directly, we recommend cutting the stationary phase and using fibers with a 2\u2010mm stationary phase. The system was tested for the analysis of tetracycline antibiotic residues, <jats:italic>viz<\/jats:italic>., tetracycline, oxytetracycline and doxycycline in soils. The overall accuracy was assessed by regression analysis of spiked samples, showing successful results at a 95% confidence level. The reproducibility, expressed as RSD, was 5.3% and the LOD of tetracycline antibiotics in soil ranged from 2.9 to 3.2\u2005\u03bcg\/kg.<\/jats:p>","DOI":"10.1002\/elps.200600429","type":"journal-article","created":{"date-parts":[[2007,3,21]],"date-time":"2007-03-21T11:43:18Z","timestamp":1174477398000},"page":"1312-1318","source":"Crossref","is-referenced-by-count":35,"title":["On\u2010line coupling of solid\u2010phase microextraction to commercial CE\u2010MS equipment"],"prefix":"10.1002","volume":"28","author":[{"given":"Bricio","family":"Santos","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bartolom\u00e9 M.","family":"Simonet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1ngel","family":"R\u00edos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Valc\u00e1rcel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,4,27]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.2166\/wqrj.1989.010"},{"key":"e_1_2_1_3_2","volume-title":"Solid Phase Microextraction","author":"Pawliszyn J.","year":"1997"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/chromsci\/44.6.291"},{"key":"e_1_2_1_5_2","doi-asserted-by":"crossref","first-page":"366","DOI":"10.1093\/chromsci\/44.6.366","volume":"44","author":"Zhen L.","year":"2006","journal-title":"J.
