Abstract
A cell analyzer and a sorting method for the cell analyzer are disclosed. Multiple optical signals generated by each of particles irradiated with light in a blood sample in a detection region are collected. The particles includes a first category of particles and a second category of particles. For each of the particles, Intensities of a first group of optical signals, which includes at least two optical signals selected from the multiple optical signals, and a pulse width of a second group of optical signals, which includes at least one optical signal selected from the multiple optical signals are acquired. For each of the particles, one or more reinforcement signals related to the particle are calculated based on an intensity of a first optical signal selected from the first group of optical signals and a pulse width of a second optical signal selected from the second group of optical signals, where the first optical signal is as same as or different from the second optical signal. The first category of particles and the second category of particles are distinguished from each other based at least partially on the one or more reinforcement signals related to each of the particles…
