(color online) Experimental results of D2O/sesame oil biphasic system by PHASICS. Sesame oil was diluted by CDCl3 with the ratio of 1:10. (a) and (b) the original and corrected 2D chemical shift contours, respectively, (c) 1D spectra extracted from 2D map with the position from 4 mm to −4 mm, (d) concentration profiles of residual water for D2O and oil versus position (Z), respectively. The interval between two adjacent points, i.e., the spatial resolution is 0.40 mm.
