By far the most important physical property of particulate samples is particle size. Measurement of particle size distributions is routinely carried out across a wide range of industries and is often a critical parameter in the manufacture of many products.

Measuring particle size distributions and understanding how they affect your products and processes can be critical to the success of many manufacturing businesses. Malvern Instruments offers leading instrumentation for all types of particle size analysis and characterization from sub-nanometer to millimeters in particle size.

Size: What is the z-average? FAQ

The z-average diameter is the mean intensity diameter i.e. it is a diameter based upon the intensity of scattered light of a material in its native state (including electrical double layers and surface structure). The z-average is derived from a Cumulants analysis of the measured correlation curve, wherein a single particle size is assumed and a single exponential fit is applied to the autocorrelation function. It is unique to dynamic light scattering and it is sensitive to the presence of aggregates/dust due to the intensity of light scattered by any larger particles present.
