Evaluation of partition measurements in liquid-liquid segmented flow.
The different configurations possible for an FIA extraction system for partition measurements have been tested and the corresponding evaluation formulae based on determinations at different phase flow ratios, verified. Increased flexibility results from the possibility of using samples dissolved in either aqueous or organic phase. Choosing the best configuration in every case makes it possible to extend the range of measurable conditional partition constants without excessive losses in precision.
