Abstract
An automated on-line sampling method was developed using microdialysis as the simultaneous sampling and sample pre-treatment technique. The extraction fraction values of microdialysis probes sampling different eicosanoids were investigated. The impact of cyclodextrins in the perfusion liquid used for sampling hydrophobic eicosanoids in biological systems was also studied. The total time for one analysis was 7.6 min allowing seven measurements per hour for monitoring kinetic changes in biological systems.
