Figure 2: Typical electropherogram (after different washing and preconditioning steps not shown here, the CE-separation starts at 300 sec) of uncomplexed and HA-complexed Eu and Cs (200 µg L-1) as CE flow marker analysed by CE-ICPMS, pH 5, c(Eu): 500 µg L-1, c(HA): 25 mg L-1, U: 30 kV, CE-electrolyte: 100 mM HAc/10 mM NaAc [38].
