3.6.3. Drop size distribution from PGSE restricted diffusion measurement
Figure 3.15 shows NMR signal attenuation of water in diluted bitumen
(sample 1, dilution ratio 2.4, with clay solids) emulsion and drop size distribution
from data fitting.

Here the diffusion time Δ is 500 ms, gradient pulse duration δ is 3 ms, range
of magnetic gradient g is 0 - 40 G∕cm. The sensitive range of drop size can be
measured by the diffusion measurement is 6 - 72 μm. The determination of the
drop size distribution consists of performing a least-square fit of the experimental
