NMR Self-Diffusion Studies of the Water and the Oil Components in a W/O/W Emulsion
The application of the pulsed field gradient NMR technique to a double emulsion is presented. This method determines the diffusion behavior of the different components of the emulsion. The details of the system studied, which is of the W/O/W type, have been taken from the literature. Information obtained pertains to the size distribution of the water droplets in both the starting emulsion and the double emulsion. In addition, the different phenomena that govern the oil diffusion in both systems have been identified and discussed.
