Description
Summary:•Recent applications of CE in seawater analytes are critically examined.•Emphasis is given to the most advantageous sample preconcentration strategies.•The method is completive from the standpoint of simplicity and speed of analysis.•Existing analytical procedures are however not always sufficiently robust.•CE is still on its way to find a routine place in marine analytical laboratories. Recent applications of capillary electrophoresis (CE) to the determination of various seawater analytes are critically examined, with the aim to reveal method’s state-of-the-art and possible future research trends in the area. Given highly developed separation and detection methodology, emphasis is given to the most advantageous sample preconcentration strategies used to evolve the method’s practical utility, particularly to low-level analytes. Analytical performance of CE applied to seawater analysis is illustrated with a selection of real-world applications published from 2006, from which it appears that the primary developmental tendency is presently confined to a transit from inorganic to organic seawater analytes.
