Pore size distribution mapping has been demonstrated using NMR cryopor
ometry in the presence of a magnetic field gradient, This novel method
is extendable to 2D and 3D mapping. It offers a unique nondestructive
method of obtaining full pore-size distributions in the range 3 to 10
0 nm at any point within a bulk sample. Copyright (C) 1996 Elsevier Sc
