Direct Determination of Oleic Acid in Soybean Oil by Capacitively Coupled Contactless Conductivity Detection Capillary Electrophoresis in an Oil-Miscible KOH/1-Propanol/Methanol Medium

Capillary electrophoresis in phytochemical analysis (2014–2017)

“…In addition, C 4 D was also applied for the detection of oleic acid in soybean oil by NACE , and determination of the content of rebaudioside A and stevioside in samples of sweeteners and beverages prepared from extracts of the plant Stevia rebaudiana Bertoni .…”

Application of capillary electrophoresis with capacitively coupled contactless conductivity detection (CE‐C4D): An update

“…Nonaqueous CE with C 4 D for the direct determination of oleic acid in soybean oil was reported by Böckel et al (). A mixture of methanol–1‐propanol (1:6 v /v) containing 4 × 10 −2 mol L −1 KOH and 10% ( v /v) ethylene glycol was used as a BGE.…”

Fatty acids analysis by capillary electrophoresis: Fundamentals, advantages and applications

“…It is important to highlight that this work was the first reported in the literature using C 4 D in the separation of linear chain FAs (Figure 2). From the year of this publication on, some other studies aimed at the determination of FAs in food matrices were developed also using C 4 D as the main detection system [16][17][18][19][20]. In this context, a review paper by Tůma et al, published in 2021, covers the use of both conventional CE and microchip electrophoresis (ME) coupled with C 4 D for the analysis of a comprehensive range of molecules, FAs included, in water, beverages, and foodstuffs [21].…”
