FIG. 21-17 Multisizer 3 COULTER COUNTER from Beckman Coulter, Inc., uses the electrical sensing zone method. 

Multiple techniques can be used to measure the particle size distribution, for example electrozone sensing, sedimentation, laser diffraction, and microscopy. With the exception of microscopy, they all require calibration and the results depend on the technique. For example, in a round-robin study reported in Reference 4, the commonly used electrical sensing zone technique (Coulter Counter) was compared to microscopy and sedimentation. The average particle size determined by the electrical sensing zone method was by about 25%... 

Introduced in 1983, this Part gives recommendations for the electrical sensing zone method (the Coulter principle). It is recommended that the primary calibration technique is that of "mass integration", where a known volume of particles under test is used to calibrate the volumetric size response directly. This allows the method to be self-calibrating and to approach being absolute.

The Electrical Sensing Zone Method (The Coulter Principle)... 

The Coulter Counter, through its various models, has become an estabi ished and we I I evaluated method of counting and sizing particles. The Coulter principle, or better, the electrical sensing zone method, has been the subject of many publications, including textbooks and the British Standard 3406. The main advantage of this method is that it yields directly a number distribution of the equivalent volume diameter. 

The electrical sensing zone method, also known as Coulter Counter method, has since its development in 1953 [1] been subject to numerous studies and applications. As a result the technique is well described, as well in textbooks [2, 3] as in manuals accompanying the instrtunents [4], and accepted as a Standard Method [5, 6, 7]. A schematic drawing of the instrument is given in figure 1.
