“…Travassos Lemos and co‐workers published two papers on the application of CE‐C 4 D for simultaneous analysis of inorganic cations and anions in virgin olive oils (Travassos Lemos, Cassella, & Jesus, ; Travassos Lemos, Pinheiro, Cassella, & Jesus, ). In the first paper the CE‐C 4 D was assessed for analysis of potassium, sodium, calcium and magnesium in virgin olive oils.…”

Capacitively coupled contactless conductivity detection (C D) has appeared as a powerful technique for the detection of compounds lacking chromogenic or fluorogenic group. Since our last review (Biomedical Chromatography 2014; 28: 1502-1506) several new capillary electrophoresis (CE)-C D methods have been reported. This review provides an update of the most recent utilization of CE-C D in the field of pharmaceutical, biomedical and food analysis covering the period from February 2014 to October 2016. The use of CE with C D in the pharmaceutical field has been shown in many papers. Examples illustrate the applicability of CE-C D in the fields of pharmaceutical, biomedical and food analysis. Finally, general conclusions and perspectives are provided.

“…Using a BGE consisting of 15 mmol L −1 HIS at pH 4.0, adjusted with lactic acid, and 0.6 mmol L −1 cetyltrimethylammonium hydroxide, the anions were separated in <3 min, as shown in Figure . LOQs in the range 0.01–0.7 mg kg −1 were obtained (Travassos Lemos et al, ).…”

“…Gas chromatography (Lee et al 2012;Lee et al 2013;Ligor et al 2008;Ryhl-Svendsen and Glastrup 2002;Sokoro et al 2007), capillary electrophoresis (Klampfl et al 2000;Kubáñ and Boček 2013;Kubáň et al 2014;Pantučkova et al 2013;Suárez-Luque et al 2006;Travassos Lemos et al 2015), and ion chromatography (Brudin et al 2010;Käkölä et al 2008;Kuo 1998;Lodi and Rossin 1995;Magne et al 1998;Rantakokko et al 2004;Walford 2002;Wojtczak et al 2013) are techniques most often used for the determination of low-molecular-mass carboxylic acids in various materials, including food products. Complications arising from the major sample components, e.g., proteins, lipids, and salts, in the examination of the samples of biological matrices, can generate the necessity of coupling of the technique with a suitable sample preparation step for their elimination.…”

Monitoring of human exposure to formic acid is important due to its high biological activity. Elevated amounts of formic acid in the human body can cause serious damage to optical nerve, respiratory failure, renal failure, deep metabolic acidosis, coma, and eventual death from cardiovascular arrest. Such symptoms are characteristic for methanol poisoning owing to rapid enzymatic conversion of methanol into formic acid of substantially higher than methanol alone toxicity. Early diagnosis of methanol consumed and formic acid produced is essential for successful medical treatment. Small amounts of methanol can be introduced into the human body with alcoholic drinks (methanol can be a by-product of distillation and fermentation processes). A fast method for the determination of formates in commercial alcoholic drinks by the use of suppressed ion chromatography (IC) with conductometric detection has been developed. The applicability of two anion-exchange columns, Metrohm Metrosep A Supp 7 and Dionex IonPac AS9-HC, for selective detection of formates in mixtures with acetates and common inorganic ions occurring in such kind of samples was examined. Quantitative isolation of formates from the matrix can be reached in less than 10 min using 3.6 mmol/L Na 2 CO 3 as an eluent. Preliminary minimizing of alcoholic matrix by the evaporation (under IR source) allows to improve the quality of chromatographic results. The evaluated amounts of formates in two different Polish commercial products, BAbsolwent vodka^and BGolden Rum,^tested in the work were in the range of 0.2-3.1 mg/L. The 96-107% recoveries of the formates from the examined samples were found out.

The development of capacitively coupled contactless conductivity detection for the two-year period from mid-2014 to mid-2016 is covered in this review. This includes a survey of fundamental studies and further developments of the measuring technique reported as well as a discussion of new applications. These mostly concern capillary electrophoresis carried out in conventional capillaries as well as on microchip electrophoresis devices. The main focus is on the determination of small non-UV-absorbing organic ions and inorganic ions in different types of samples of clinical, nutritional or environmental interest. Outside of electrophoresis contactless conductivity detection is finding uses in detection in column chromatography, flow-injection analysis and industrial applications.
