Abstract
In particle analysis applied to blood cells, use is made of a distinguishing parameter which is the ratio of pulse height to pulse width derived from individual pulses generated in response to detection of corresponding individual particles. The distribution of the distinguishing parameter is plotted on a distribution of pulse height and pulse width, and a three-dimensional display of pulse height, pulse width and the distinguishing parameter is used in analyzing the particles.
