The ability of this ruthenium coating to electrocatalyze the oxidation of aliphatic and heterocyclic amines, as well as their amino acid precursors, was checked by using ethanolamine, tryptamine and tryptophane as prototype compounds and adopting a 25\u2009mM sulphuric acid as the electrolyte in the detection cell, where a constant potential of 1.05\u2009V versus Ag\/AgCl, 3\u2009M KCl was applied to the modified working electrode. Optimization of parameters affecting both detection and separation steps led to satisfactory separations when performed by using a 20\u2009mM phosphate running buffer (pH 2.5) and applying a high voltage of 2.5\u2009kV both in the separation and in the electrokinetic injection (duration 4\u2009s). The recorded peaks were characterized by good repeatability (RSD\u22643.6%), high sensitivity and a wide linear range. Detection limits of 23\u2009\u03bcM (1.4\u2009mg\/L), 27\u2009\u03bcM (4.3\u2009mg\/L) and 34\u2009\u03bcM (6.8\u2009mg\/L) were inferred for ethanolamine, tryptamine and tryptophane, respectively. The approach proposed here was also applied for the analysis of some double malt dark beers spiked with a controlled amount of the analytes considered.<\/jats:p>","DOI":"10.1002\/elps.201000690","type":"journal-article","created":{"date-parts":[[2011,3,16]],"date-time":"2011-03-16T03:41:42Z","timestamp":1300246902000},"page":"906-912","source":"Crossref","is-referenced-by-count":45,"title":["A modified electrode for the electrochemical detection of biogenic amines and their amino acid precursors separated by microchip capillary electrophoresis"],"prefix":"10.1002","volume":"32","author":[{"given":"Nicol\u00f2","family":"Dossi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosanna","family":"Toniolo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Pizzariello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabina","family":"Susmel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gino","family":"Bontempelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,3,16]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0963-9969(96)00066-X"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-1605(90)90040-C"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-1605(95)00032-1"},{"key":"e_1_2_6_5_2","first-page":"248","volume-title":"Pathogens and Toxins in Food: Challenges and Interventions","author":"Koutsoumanis K.","year":"2009"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(03)01068-9"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(03)00610-1"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(95)00961-2"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(96)00925-9"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.261.5123.895"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00067a015"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200700517"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2009.04.081"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1385\/1-59745-076-6:85"},{"key":"e_1_2_6_15_2","first-page":"1133","volume":"2005","author":"Wang J.","journal-title":"Electroanalysis"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200700208"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2008.08.016"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelechem.2006.10.019"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200800346"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00089a012"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.1150160182"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(03)00927-0"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0308-8146(03)00223-1"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1039\/B407418A"},{"key":"e_1_2_6_25_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00097a017"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(01)95772-3"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00116a020"},{"key":"e_1_2_6_28_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0728(95)03837-7"},{"key":"e_1_2_6_29_2","doi-asserted-by":"publisher","DOI":"10.1002\/elan.1140010607"},{"key":"e_1_2_6_30_2","doi-asserted-by":"publisher","DOI":"10.1002\/elan.1140050806"},{"key":"e_1_2_6_31_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(94)80077-4"},{"key":"e_1_2_6_32_2","doi-asserted-by":"publisher","DOI":"10.1002\/elan.1140060209"},{"key":"e_1_2_6_33_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(02)00075-4"},{"key":"e_1_2_6_34_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelechem.2003.11.040"},{"key":"e_1_2_6_35_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0728(87)85116-1"},{"key":"e_1_2_6_36_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0728(92)80007-Q"},{"key":"e_1_2_6_37_2","volume-title":"Advanced Inorganic Chemistry","author":"Cotton F.
