Molecular transport across a water-organic liquid interface formed parallel to the side wall of a microchannel on microchips has been studied using methyl red as model compound and cyclohexane and n-octanol as organic solvents. The molecular transport was monitored by thermal lens microscopy and the kinetics of the process was studied for different concentrations and flow velocities. The influence of physico-chemical interactions between the model compound and organic solvents on liquid-liquid interface was demonstrated in the microspace and corresponding partition coefficients were calculated which confirmed the experimental results.
