The graph shows that the distribution is cut off at the large size end. Clearly there
is a significant amount of material at sizes above 900µm. Not only is this material
missed in the measurement but the light scattered by that material also distorts
the measurement of the material which is in the range. For such a material, the
4-3500µm range (1000mm lens on the Mastersizer S) would be more suitable as
shown in the second graph below.
