“…A similar approach was used by Wuethrich et al. for the analysis of eight penicillins and sulfonamides with ESI‐MS detection. The micellar solution was 5 mM CTAB in 50 mM ammonium acetate at pH 9 and the BGE was 50 mM ammonium acetate at pH 9 in 75% MeOH.…”

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.

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.

This paper reviews recent 5-years application researches using online sample preconcentration (OSP) methods in capillary electrophoresis (CE) coupled with mass spectrometry (MS). CE-MS has excellent analytical features such as high-resolution separation, rapid analysis time, low sample consumption, and small consumption of organic solvents. Recently, low flow-rate interface for electrospray ionization has been developed and zmol-level sensitivity has been achieved. However, application of CE-MS has still been prevented due to small capacity of sample injection volume. OSP methods have been developed to address this issue and up to 5,000-fold sensitivity improvement was obtained so far. Various application has been carried out such as proteomics, metabolomics, and glycomics, and CE-MS attracts much attention as the highest-performance analytical tool for small-volume bioanalysis. Taking account of further progress in CE-MS, smart and practical application of OSP methods will be more important in various analytical fields.
