In 2010 Micromeritics
will begin presenting a series of webinars that will highlight applications,
theory, and instrumentation for a variety of materials characterization techniques.
The first in this series of technical presentations will cover the Elzone electrical
sensing zone particle size/count technique and its pharmaceutical applications
with a live webinar on February 4 at 11 AM EST.
Unlike many particle sizing techniques, electrical sensing zone (Coulter principle)
data are unaffected by samples composed of particles having an assortment of
optical properties, densities, and shapes. Size distribution is determined by
analyzing, one at a time, each particle from a representative subset of the
introduced sample quantity. This particle-by-particle analysis technique provides
accurate particle count data and, when combined with Micromeritics’ precision
volume metering option, provides accurate number concentration data. Micromeritics’
Elzone quickly and accurately determines the size, number, concentration, and
mass of a wide variety of materials.
The electrical sensing zone technique is applicable to a wide variety of pharmaceutical
applications that include population distribution of cells for tissue cultures
and for blood cell counting, determination of particle size which is critical
for API and excipient dissolution, obtaining valuable information about trace
particle contamination, and many more. The Elzone has been used for ensuring
a proper blend prior to tableting with particle size and concentration data,
and in development and quality control of the coating process for controlled
