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.

“…Most of them are not particularly suitable for the analytical control due to limited sensitivity or specificity. The analytical techniques that have been reported in literatures for analyzing UV filters in cosmetics [15,[18][19][20][21][22][23][24][25][26][27][28][29][30][31], environmental samples [32][33][34][35][36][37] and aquatic products [38] mainly include spectrophotometry [18], nuclear magnetic resonance spectroscopy [19], Raman spectroscopy [20], derivative ultraviolet spectrometry [21], chemiluminescence [22], micellar electrokinetic chromatography [23,24], electrochemistry [25], supercritical fluid chromatography with ultraviolet detection [26] or mass spectrometric detection, gas chromatography with flame ionization [27], mass spectrometric [27,28,[33][34][35][36][37] or tandem mass spectrometric [15] detection and high-performance liquid chromatography with ultraviolet detection [29][30][31] or tandem mass spectrometry…”

“…MEKC has been performed according to the different partition abilities of analytes . In a previous study in our laboratory, AFMC‐MEKC was preliminary established to analyze ultraviolet absorbents . However, many factors can influence the CE separation; optimizing the CE condition using a single‐variable approach would thus be rather laborious and would omit the interaction between each factor.…”

The operating parameters that affect the performance of the online preconcentration technique "analyte focusing by micelle collapse-MEKC (AFMC-MEKC)" were examined using a multivariate approach involving experimental design to determine the sunscreen agents in cosmetics. Compared to the single-variable approach, the advantage of the multivariate approach was that many factors could be investigated simultaneously to obtain the best separation condition. A fractional factorial design was used to identify the fewest significant factors in the central composite design (cCD). The cCD was adopted for evaluating the location of the minimum or maximum response in this study. The influences of the experimental variables on the response were investigated by applying a chromatographic exponential function. The optimized condition and the relationship between the experimental variables were acquired using the JMP software. The ANOVA analysis indicated that the Tris pH value, SDS concentration, and ethanol percentage influenced the separation quality and significantly contributed to the model. The optimized condition of the running buffer was 10 mM Tris buffer (pH 9.5) containing 60 mM SDS, 7 mM γ-CD, and 20% v/v ethanol. The sample was prepared in 100 mM Tris buffer (pH 9.0) containing 7.5 mM SDS and 20% v/v ethanol. The SDS concentration in the sample matrix was slightly greater than the CMC value that makes the micelle be easily collapsed and the analytes be accumulated in the capillary. In addition, sunscreen agents in cosmetics after 1000-fold dilution were successfully determined by AFMC-MEKC.
