Hi,
        I wonder if anyone out there could offer any useful
suggestions.
A major part of my project is to construct a partition
device based on Flow Injection Analysis. Basically,
under HPLC conditions (to mimic petroleum reservoir conditions)
I want to determine the partition coefficients of selected
compounds in solvent/water and oil/water systems.
At present, I understand how to introduce the solvent and
water into a mixing column where the spiked compounds will
partition between the two phases under temperature and
pressure conditions typical of petroleum reservoirs.
However, I envisage there will be problems separating the
solvent and water upon leaving the mixing column again
under temperature (c. 90C) and pressure.
        Gravity separation has been applied so far.

                                .——
                                | sssss —->                s = solvent
                                | s.—
                                | s|
                                | s|
                                | s|
                        ——–’ s|
(Mixing column)  —->  swswswswsw |
                        ——–. w|
                                | w|
                                | w|
                                | w|
                                | w’—
                                | wwwww —->                w = water
                                ‘——
As in the diagram to determine partition coefficients
it would be simple to determine the concentrations
of compounds by analysis of the separated oil and water.
However, its not so simple as the picture depicts.
        Does anyone know any other physical methods to
obtain the said fractions? Or does anyone have experience
with such equipment? The Flow injection analysis method is
commonly used in the water and pharmaceutical disciplines.
I look forward to any useful comments or ideas.
