Dec 11,  · The Electrical Sensing Zone technique aka. The Electrical Sensing Zone technique (also known as the Coulter Counter) has been used as a method of particle size measurement since it’s development in the ’s. Originally developed for counting blood cells, it was quickly realised that the ‘Coulter Counter’ could be of great help in particle size. Suboptimal conjugation will affect the sensitivity and dynamic range of the assay. A method commonly used to determine bead concentration is by particle counting using a Coulter-based flow cytometry device such as a Coulter Counter. Flow cytometry–based devices measure particles in a stream using impedance technology. Dec 11,  · The Electrical Sensing Zone technique (also known as the Coulter Counter) has been used as a method of particle size measurement since it’s development in the ’s. Originally developed for counting blood cells, it was quickly realised that the ‘Coulter Counter’ could be of great help in particle size analysis of almost any powder.
