Capacitively coupled contactless conductivity detection was employed as detection\u00a0mode that\u00a0makes CE a simple and economic tool for\u00a0money\u2010constrained laboratories. The developed\u00a0method is straightforward and user\u2010friendly. It offers good sensitivity and sufficient selectivity for the routine assay of the selected penicillins. The repeatabilities were &lt;1.9% RSD for relative peak areas and &lt;1% RSD for\u00a0migration times for all the analytes. The\u00a0method showed good linearity (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0&gt;\u00a00.995) within the 80\u2013120% range of the target concentration (0.5\u00a0mg\/mL) for each antibiotic. The accuracy of the\u00a0method, evaluated by standard fortification at three levels, was good for all the analytes. An extended robustness study was performed by varying \u00b110% of the optimum value of TRIS concentration, <jats:sc>l<\/jats:sc>\u2010histidine concentration and temperature in a full factorial design at two levels. This was to evaluate larger than usual variability of factors on the assay value, in order to better cover potential global variance in lab conditions and equipment. Finally, the\u00a0method was applied for the determination of percent (%) content of all antibiotics in available formulations.<\/jats:p>","DOI":"10.1002\/elps.201800033","type":"journal-article","created":{"date-parts":[[2018,4,12]],"date-time":"2018-04-12T05:46:49Z","timestamp":1523512009000},"page":"2521-2529","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["A simple, low\u2010cost and robust capillary zone electrophoresis\u00a0method with capacitively coupled contactless conductivity detection for the routine determination of four selected penicillins in money\u2010constrained laboratories"],"prefix":"10.1002","volume":"39","author":[{"given":"Prasanta","family":"Paul","sequence":"first","affiliation":[{"name":"KU Leuven\u2010University of Leuven Pharmaceutical Analysis Department of Pharmaceutical and Pharmacological Sciences  Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cari","family":"S\u00e4nger\u2010van de Griend","sequence":"additional","affiliation":[{"name":"Analytical Pharmaceutical Chemistry Uppsala University  Husargatan Sweden"},{"name":"Kantisto BV  Calenburglaan The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erwin","family":"Adams","sequence":"additional","affiliation":[{"name":"KU Leuven\u2010University of Leuven Pharmaceutical Analysis Department of Pharmaceutical and Pharmacological Sciences  Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann","family":"Van Schepdael","sequence":"additional","affiliation":[{"name":"KU Leuven\u2010University of Leuven Pharmaceutical Analysis Department of Pharmaceutical and Pharmacological Sciences  Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,5,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpba.2010.07.026"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.201600235"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac303328g"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2010.03.014"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodcont.2017.02.020"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2016.07.032"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2016.06.050"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/elan.200503237"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200406059"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200406060"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200900217"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.201000354"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200305476"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200406156"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2007.05.048"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/pmic.201200378"},{"key":"e_1_2_8_18_1","first-page":"415","volume":"384","author":"McCord B.","year":"2008","journal-title":"ethods Mol.
