The concept of renewable microcolumns within the conduits of an automated single injection lab-on-valve system was exploited in a sorption/elution fashion using sorbents of hydrophobic nature. The scheme's practical applicability was demonstrated for the electrothermal atomic absorption spectrometry determination of trace level concentrations of cadmium in complex matrices. Statistical comparisons between the proposed procedure and certified values revealed no significant differences at the 95% confidence level.
