Biological particle analyzer and method of analyzing biological particles

摘要

A method of analyzing biological particles for a biological particle analyzer includes outputting a first detection result when at least one particle has arrived at the first detection area, outputting a second detection result to the control module when the particles have arrived at the second detection area, and determining when to turn on or off the light emission source and outputting a control signal to turn on or off the light emission source according to the first detection result, wherein a control module is configured to calculate a turn-on time according to different particle characteristics and an average velocity of the at least one particle, and the light emission source is turned on only when the at least one particle is being tested during the turn-on time.

1. A method of analyzing biological particles for a biological particle analyzer comprising a light emission source and a microchannel for containing a particle flowing inside the microchannel, the microchannel comprising a first detection area at an upstream location, a second detection area located at a downstream location and an excitation area at the downstream location lighted by the light emission source, the method comprising:
by a first detection circuit of the biological particle analyzer, outputting a first detection result when at least one particle has arrived at the first detection area; by a second detection circuit of the biological particle analyzer, outputting a second detection result to the control module when the particles have arrived at the second detection area; and by a control module of the biological particle analyzer, determining when to turn on or off the light emission source and outputting a control signal to turn on or off the light emission source according to the first detection result; wherein the control module is configured to calculate a turn-on time according to different particle characteristics and an average velocity of the at least one particle, and the light emission source is turned on only when the at least one particle is being tested during the turn-on time; wherein when the first detection result indicates that a first particle of the at least one particle has arrived at the first detection area, the control module outputs the control signal to the light emission source to turn on the light emission source, and when the second detection result indicates that the first particle has arrived at the second detection area, the control module outputs the control signal to the light emission source to turn off the light emission source; wherein the control module further comprises a counter for recording a first particle number when the first particle of the at least one particle has arrived at the first detection area and a second particle number when the first particle of the at least one particle has arrived at the second detection area to determine to turn on or off the light emission source.
