“When proper measurements are made, the parameters of the size distribution most often obtained -- the inverse z-average moments -- are not the usually reported parameters of a size distribution.”

“The calculated number average molecular weight is generally very dependent upon the low molecular weight material in the distribution, whilst the z-average is more affected by the high molecular weight material present.”

“The harmonic average lies in between the z-average and the weight-average particle size.”
