Dynamic light scattering is often used but presence of a small number of aggregates can greatly influence the size distribution. Electrospray scanning mobility\u00a0particle sizer (ES\u2013SMPS) is rapidly emerging as an alternative method in colloidal science. However, a major limitation is the use of silica-coated capillaries, which are negatively charged at pH &amp;gt; 3,\u00a0and\u00a0therefore making its use difficult for positively charged nanoparticles. In this work, we have developed the\u00a0polyether ether ketone (PEEK) capillary for ES\u2013SMPS, which removes this limitation because it carries no charge. We have shown that the new capillary not only produced equally good particle size distributions for negatively charged particles (SiO2, Au, and latex) as obtained with silica capillaries, but also precise particle size distributions for positively charged particles (TiO2). Moreover, the PEEK capillaries\u00a0are\u00a0much cheaper than the silica capillaries. Thus, the results shown in this paper strengthen the development of the ES\u2013SMPS method as a versatile method for determining the particle size distributions of colloidal\u00a0sols directly from solution.<\/jats:p>","DOI":"10.1021\/acsomega.8b03264","type":"journal-article","created":{"date-parts":[[2019,1,14]],"date-time":"2019-01-14T13:02:27Z","timestamp":1547470947000},"page":"1151-1156","source":"Crossref","is-referenced-by-count":3,"title":["Development and Evaluation of Polyether Ether Ketone\n(PEEK) Capillary for Electrospray"],"prefix":"10.1021","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2957-2021","authenticated-orcid":true,"given":"Christian","family":"So\u0308gaard","sequence":"first","affiliation":[{"name":"University of Gothenburg , , Kemiva\u0308gen 10 , ,","place":["Gothenburg, Sweden, 41296"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5388-4821","authenticated-orcid":true,"given":"Isabelle","family":"Simonsson","sequence":"additional","affiliation":[{"name":"University of Gothenburg , , Kemiva\u0308gen 10 , ,","place":["Gothenburg, Sweden, 41296"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zareen","family":"Abbas","sequence":"additional","affiliation":[{"name":"University of Gothenburg , , Kemiva\u0308gen 10 , ,","place":["Gothenburg, Sweden, 41296"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2019,1,14]]},"reference":[{"key":"2026090415103533900_cit1","doi-asserted-by":"publisher","first-page":"677","DOI":"10.1002\/(SICI)1096-9888(199707)32:73.0.CO;2-G","article-title":"Electrospray:\nprinciples and practice","volume":"32","author":"Gaskell","year":"1997","journal-title":"J.
