“…Belal et al. reported a simple and specific sweeping‐MEKC method with dynamic pH junction for the analysis of pharmaceutical mixtures containing paracetamol, caffeine, drotaverine and dipyrone. The BGE consisted of 10 mM disodium tetraborate buffer at pH 9.30 with 75 mM SDS.…”

Electrophoretic sample stacking comprises a group of capillary electrophoretic techniques where trace analytes from the sample are concentrated into a short zone (stack). This paper is a continuation of our previous reviews on the topic and brings a survey of more than 120 papers published approximately since the second quarter of 2016 till the first quarter of 2018. It is organized according to the particular stacking principles and includes chapters on concentration adjustment (Kohlrausch) stacking, on stacking techniques based on pH changes, on stacking in electrokinetic chromatography and on other stacking techniques. Where available, explicit information is given about the procedure, electrolyte(s) used, detector employed and sensitivity reached. Not reviewed are papers on transient isotachophoresis which are covered by another review in this issue.

“…The samples were pharmaceutical formulations, food and beverages, and human serum and urine. The sample preparations included homogenization and dilution of the food and beverage samples , protein precipitation and further SPE treatment of the biological samples. Detection of the analytes was performed using direct UV or indirect detection at wavelengths of 200–257 nm.…”

One of the most cited limitations of capillary (and microchip) electrophoresis is the poor sensitivity. This review continues to update this series of biennial reviews, first published in Electrophoresis in 2007, on developments in the field of on-line/in-line concentration methods in capillaries and microchips, covering the period July 2014-June 2016. It includes developments in the field of stacking, covering all methods from field amplified sample stacking and large volume sample stacking, through to isotachophoresis, dynamic pH junction, and sweeping. Attention is also given to on-line or in-line extraction methods that have been used for electrophoresis.

“…The sweeping‐MEKC with dynamic pH junction and RFGE (Retention Factor Gradient Effect) was developed for the simultaneous analysis of four different analytes (i.e., drotaverine hydrochloride and caffeine combined with paracetamol or dipyrone) in pharmaceutical formulations. Signal enhancement of up to eightfold was achieved by the proposed techniques [119]. Simultaneous analysis of tricyclic antidepressant and β‐blockers (i.e., alprenolol, labetalol, and propranolol) in wastewater was also improved using sweeping–MEKC with signal enhancements of up to 305‐fold [120].…”

This review aims to illustrate sensitivity enhancement methods in capillary electrophoresis (CE) and their applications for pharmaceutical and related biochemical substance analyses. The first two parts of the article describe the introduction and principle of CE. The main part focuses on strategies for sensitivity improvement in CE including detector and capillary technologies and preconcentration techniques. Applications of these techniques for pharmaceutical and biomedical substance analyses are surveyed during the years 2018-2021.
