The aim of the current study was to optimise and validate the methodology for determination of γ‐hydroxybutyric acid (GHB) in saliva by CE combined with a contactless conductivity detector (C4D) and indirect UV absorbance detection (λABS = 210 nm). The optimized BGE, consisting of 8.5 mM maleic acid, 17 mM arginine, 255 μM cetyltrimethylammonium bromide (CTAB), and 15% acetonitrile, was evaluated...
In this article, optimization of BGE for simultaneous separation of inorganic ions, organic acids, and glutathione using dual C4D‐LIF detection in capillary electrophoresis is presented. The optimized BGE consisted of 30 mM 2‐[4‐(2‐hydroxyethyl)piperazin‐1‐yl]ethanesulfonic acid, 15 mM 2‐amino‐2‐hydroxymethyl‐propane‐1,3‐diol, and 2 mM 18‐crown‐6 at pH 7.2 and allowed simultaneous separation of ten...
