Biogenic monoamines and amino acids were chosen as model analytes to evaluate the analytical possibilities of this approach. The derivatization conditions and separation parameters for the biogenic amines were optimized in detail. The derivatization was performed at 30\u00b0C for 6\u00a0min in boric acid buffer (pH 8.0). The derivatives were baseline\u2010separated in 15\u00a0min with 25\u00a0m<jats:sc>M<\/jats:sc> boric acid running buffer (pH 9.0), containing 24\u00a0m<jats:sc>M<\/jats:sc> SDS and 12.5% v\/v acetonitrile. The concentration detection limit for biogenic amines reaches 8\u00d710<jats:sup>\u221211<\/jats:sup>\u00a0mol\u00b7L<jats:sup>\u22121<\/jats:sup> (signal\u2010to\u2010noise ratio = 3). The application of CE in the analysis of the SAMF\u2010derivatized amino acids was also exploited. The optimal running buffer for amino acids suggested that weak acidic background electrolyte offered better separation than the basic one. The proposed method was applied to the determination of biogenic amines in three different beer samples with satisfying recoveries varying from 92.8% to 104.8%. Finally, comparison of several fluorescein\u2010based probes for amino compounds was discussed. With good labeling reaction, excellent photostability, pH\u2010independent fluorescence (pH 4\u20139), and the resultant widely suited running buffer pH, SAMF has a great prospect in the determination of amino compounds in CE.<\/jats:p>","DOI":"10.1002\/elps.200410227","type":"journal-article","created":{"date-parts":[[2005,4,8]],"date-time":"2005-04-08T07:11:03Z","timestamp":1112944263000},"page":"1954-1962","source":"Crossref","is-referenced-by-count":21,"title":["Analytical potential of 6\u2010oxy\u2010(<b><i>N<\/i><\/b>\u2010succinimidyl acetate)\u20109\u2010(2'\u2010methoxycarbonyl) fluorescein for the determination of amino compounds by capillary electrophoresis with laser\u2010induced fluorescence detection"],"prefix":"10.1002","volume":"26","author":[{"given":"Liwei","family":"Cao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huashan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,5,4]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/bmc.1130060511"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2003.09.025"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0378-4347(93)80487-O"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2003.08.013"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(03)00558-2"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4347(00)00286-3"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4347(98)00070-X"},{"key":"e_1_2_1_9_2","first-page":"3208","volume":"20","author":"Karcher A.","year":"1999","journal-title":"Electrophoresis"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/1522-2683(200202)23:4<559::AID-ELPS559>3.0.CO;2-G"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200405941"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200305692"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200305660"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200305635"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac0415859"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1522-2683(20000401)21:7<1239::AID-ELPS1239>3.0.CO;2-6"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1522-2683(20000401)21:7<1267::AID-ELPS1267>3.0.CO;2-C"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(92)85174-R"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1007\/s002160000654"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02290261"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02290262"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1002\/1522-2683(200204)23:7\/8<1096::AID-ELPS1096>3.0.CO;2-E"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/1522-2683(200207)23:14<2333::AID-ELPS2333>3.0.CO;2-5"},{"key":"e_1_2_1_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0270(00)00371-X"},{"key":"e_1_2_1_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(03)00637-X"},{"key":"e_1_2_1_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1570-0232(02)01032-2"},{"key":"e_1_2_1_27_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(95)00464-X"},{"key":"e_1_2_1_28_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(98)00165-4"},{"key":"e_1_2_1_29_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4347(00)00092-X"},{"key":"e_1_2_1_30_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00323009"},{"key":"e_1_2_1_31_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-1575(03)00104-2"},{"key":"e_1_2_1_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(96)00693-0"},{"key":"e_1_2_1_33_2","doi-asserted-by":"crossref","first-page":"259","DOI":"10.4315\/0362-028X-57.3.259","volume":"57","author":"Maijala R.","year":"1994","journal-title":"J.
