“…As an alternative approach for achieving efficient sample preconcentration in FASS, large-volume sample stacking (LVSS) has been utilized with the increase in the sample injection volume. As summarized in Table 3, LVSS has been employed to the determination of rotenone [36], sesquiterpene alkaloids [37], phenolic compounds [38], anionic micropollutants [39], parabens [40], antiepileptic drugs [41], clonidine and cyproheptadine [42]. In FASS, a large volume injection of the sample reduces an effective separation length, which sometimes causes poor separation.…”

This review highlights recent applications of on-line sample preconcentration techniques in capillary electrophoresis (CE) from 2019 to 2021. Various preconcentration techniques based on the analyte velocity change in two or three discontinuous solutions system including field-amplified sample stacking, transient isotachophoresis, pH-mediated stacking, sweeping, and their modified and combined techniques have been employed to enrich and separate biological, environmental, food samples, and so on, in CE. More than 60 published research articles collected from Scopus databases described the dynamic on-line sample preconcentration techniques. This review provides comprehensive tables listing the applications of the on-line sample preconcentration techniques.

“…Benefitting from its flexibility and tolerance to the high salt environment, ABS method has been applied to various biological samples, such as plasma, brain microdialysate, and saliva, by using the acid zone as a solid barrage to concentrate weak acids [24,25]. As a convenient online enrichment method used in recent years, the sensitivity of LVSS can be easily improved by 10-to 1000-fold based on the injecting large-volume sample into a capillary and stacking by switching the polarity [26][27][28].…”

A chiral analytical method was proposed based on capillary electrophoresis with laser-induced fluorescence detection coupled with microwave-assisted derivatization for the simultaneous baseline separation and sensitive detection of four stereoisomers of 3-hydroxyaspartate. The derivatization reaction of 3hydroxyaspartate with 4-chloro-7-nitrobenzo-2-oxa-1,3-diazole was greatly accelerated by microwave irradiation. Under the optimized conditions, the derivatization yield was increased by 20% and the derivatization time was shortened by 20 min when compared with those from conventional water bath heating. In addition, the sensitivity was improved by online sample concentration methods. The detection limit of l-threo-3-hydroxyaspartate obtained by large-volume sample stacking with polarity switching was 5.3 nmol/L, which was around 1000-fold lower than that of the capillary electrophoresis/laser-induced fluorescence without stacking. The excellent analytical performance in terms of linearity and precision was also achieved. Furthermore, the developed method was successfully applied to the determination of 3-hydroxyaspartate in the spiked urine, and satisfactory recoveries were obtained ranging from 90.5 to 107.0%.
