Parameters of two different off-line preconcentration methods (solid phase extraction SPE, and concentrator columns) were tested and optimised. Compared with SPE columns, the concentrator column AC15 was chosen as the best choice for the next optimization followed by separation and detection by ion chromatography (IC). The sensitive method for determination of 7 DCAs (oxalic, malonic, succinic, maleic, glutaric, pimelic and azelaic acid) was devised with detection limits of 0.12-0.40 nM. The presented system describes an alternative on-line method usable for automated monitoring of selected analytes.
