The purpose of this invention is to facilitate the spectral determination of undesirable water dispersed in an immiscible fluid by forming a solution through the addition of a third component in which the components of the immiscible system are mutually and simultaneously soluble. A specific application of this invention is the quantitative determination of water in Navy Special fuel oil. Examples of suitable solvents to solubilize the immiscible fuel are N-ethyl morpholine, tetrahydrofuran, bis2-ethoxy ethyl ether and mixtures thereof, although not necessarily limited thereto.
