Particle sizing is a rapidly growing field, not only because of its importance in a great variety of technological applications but also due to its outstanding relevance to numerous areas of scientific research. The currently available instruments to measure particle‐size distributions are many and varied, the results often being dependent on the measuring technique used. It is thus essential to understand the physical principles behind each technique in order to make an adequate choice. Electrozone sensing, a widely used method of particle‐size analysis, constitutes the main topic of this paper. A general description of its operating principle is provided, followed by some practical considerations mainly concerning sample preparation and the selection of electrolyte solutions and aperture tubes. Being a technique that requires prior calibration, emphasis is placed on the calibration procedures. The section dedicated to the measurement of special materials also reviews some recent improvements of this technique. Finally, a list of commercially available equipment is supplied, together with its most relevant features.

The electrical sensing zone technique is long established, well researched and widely used. It is often used as a reference method against which others are compared or calibrated. This position should not be allowed to disguise the potential which exists for still greater accuracy and versatility. In this paper the use of the hydrodynamic focussing technique is evaluated and an experimental comparison is made with a normal Coulter stand for several samples. It is clearly shown that hydrodynamic focussing enables higher resolution and accuracy to be obtained for materials with narrow or unusual particle size distributions.
