The instrument is based on pneumatic pressurization and does not require a conventional pump. The required pressures and flow rates for the different steps of the injection and flushing processes are produced with the help of two flow restrictors. The device is implemented on a microfluidic breadboard with dimensions of ca. 13 \u00d7 20 cm and employs miniature valves. Nine inorganic cations, namely NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup><jats:sub>,<\/jats:sub> K<jats:sup>+<\/jats:sup>, Na<jats:sup>+<\/jats:sup>, Ca<jats:sup>2+<\/jats:sup>, Mg<jats:sup>2+<\/jats:sup>, Mn<jats:sup>2+<\/jats:sup>, Sr<jats:sup>2+<\/jats:sup>, Li<jats:sup>+<\/jats:sup>, and Ba<jats:sup>2+<\/jats:sup>, could be separated in a capillary of 10 \u03bcm inner diameter and 6 cm effective length within 25 s. Following a reduction of the effective length to 4\u00a0cm, still five inorganic cations could be separated in a time span of 12\u00a0s. The repeatability of peak areas was better than 3.1\u00a0% and limits of detection between 3.5 and 5.5 \u03bcM were achieved.<\/jats:p>","DOI":"10.1002\/elps.201800250","type":"journal-article","created":{"date-parts":[[2018,8,28]],"date-time":"2018-08-28T07:24:13Z","timestamp":1535441053000},"page":"410-413","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Injection system for fast capillary electrophoresis based on pressure regulation with flow restrictors"],"prefix":"10.1002","volume":"40","author":[{"given":"Jasmine S.","family":"Furter","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Basel  Basel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7506-5971","authenticated-orcid":false,"given":"Peter C.","family":"Hauser","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Basel  Basel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,9,2]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2010.03.014"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2016.12.029"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2016.04.015"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.elecom.2006.04.009"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1039\/B606761A"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00216-005-3063-1"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2016.01.029"},{"key":"e_1_2_4_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2014.10.085"},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2014.05.046"},{"key":"e_1_2_4_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac303328g"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/b108884j"},{"key":"e_1_2_4_13_1","doi-asserted-by":"publisher","DOI":"10.1039\/C2LC20799K"},{"key":"e_1_2_4_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/elan.201100264"},{"key":"e_1_2_4_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-1497.2001.04189.x"}],"container-title":["ELECTROPHORESIS"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Felps.201800250","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/elps.201800250","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T08:28:41Z","timestamp":1760516921000},"score":1,"resource":{"primary":{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/10.1002\/elps.201800250"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,2]]},"references-count":14,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2019,2]]}},"alternative-id":["10.1002\/elps.201800250"],"URL":"https:\/\/doi.org\/10.1002\/elps.201800250","archive":["Portico"],"relation":{},"ISSN":["0173-0835","1522-2683"],"issn-type":[{"value":"0173-0835","type":"print"},{"value":"1522-2683","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,2]]},"assertion":[{"value":"2018-06-22","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-08-22","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-09-02","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
