These systems have been employed as a simple, versatile, and cost\u2010effective analytical tool. CE\u2010C<jats:sup>4<\/jats:sup>D devices, whose principle is based on the control of the ion movements under an electrical field, can be constructed even with a modest financial budget and limited infrastructure. A featured application was developed for quality control of antimicrobial drugs using CE\u2010C<jats:sup>4<\/jats:sup>D, with most recent work on determination of aminoglycoside and glycopeptide antibiotics being communicated. For aminoglycosides, the development of CE\u2010C<jats:sup>4<\/jats:sup>D methods was adapted to two categories. The first one includes drugs (liquid or powder form) for intravenous injection, containing either amikacin, streptomycin, kanamycin A, or kanamycin B. The second one covers drugs for eye drops (liquid or ointment form), containing either neomycin, tobramycin, or polymyxin. The CE\u2010C<jats:sup>4<\/jats:sup>D method development was also made for determination of some popular glycopeptide antibiotics in Vietnam, including vancomycin and teicoplanin. The best detection limit achieved using the developed CE\u2010C<jats:sup>4<\/jats:sup>D methods was 0.5\u00a0mg\/L. Good agreement between results from CE\u2010C<jats:sup>4<\/jats:sup>D and the confirmation method (HPLC\u2010 Photometric Diode Array ) was achieved, with their result deviations less than 8% and 13% for aminoglycoside and glycopeptide antibiotics, respectively.<\/jats:p>","DOI":"10.1002\/elps.202000163","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T12:35:57Z","timestamp":1598618157000},"page":"1980-1990","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Low\u2010cost and versatile analytical tool with purpose\u2010made capillary electrophoresis coupled to contactless conductivity detection: Application to antibiotics quality control in Vietnam"],"prefix":"10.1002","volume":"41","author":[{"given":"Thai Binh","family":"Le","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, University of Science Vietnam National University, Hanoi  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter C.","family":"Hauser","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Basel  Basel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Ngoc Mai","family":"Pham","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, University of Science Vietnam National University, Hanoi  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Lan Phuong","family":"Kieu","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, University of Science Vietnam National University, Hanoi  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Phuong Quynh","family":"Le","sequence":"additional","affiliation":[{"name":"Institute of Natural Product Chemistry Vietnam Academy of Science and Technology  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quoc Anh","family":"Hoang","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, University of Science Vietnam National University, Hanoi  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dinh Chi","family":"Le","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Toxicology Hanoi University of Pharmacy  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Anh Huong","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, University of Science Vietnam National University, Hanoi  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4877-258X","authenticated-orcid":false,"given":"Thanh Duc","family":"Mai","sequence":"additional","affiliation":[{"name":"CNRS, Institut Galien Paris\u2010Saclay Universit\u00e9 Paris\u2010Saclay  Ch\u00e2tenay\u2010Malabry France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,6]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.analchem.5b04125"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.analchem.8b00015"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1088\/0957-0233\/24\/4\/042001"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpba.2018.06.033"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.teac.2018.03.001"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.trac.2018.03.007"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5EM00362H"},{"key":"e_1_2_8_9_1","first-page":"273","volume":"1","author":"Duong H.
