System, storage mediums, and methods for identifying particles in flow

A flow cytometer, comprising:

• a particle flow path;
• an illumination system configured to direct light toward multiple and distinct interrogation points of the particle flow path;
• a plurality of collectors respectively configured to gather light from an interrogation region comprising the interrogation point and further configured to generate signals representative of a degree of light gathered;
• and
• an examination system comprising a processor and program instructions executable by the processor for:
• receiving said signals;
• comparing received signals of at least two collectors to predetermined signal ranges associated with a specific particle set;
• identifying a particle of the specific particle set upon detecting signal pulses that respectively fit within the predetermined signal ranges;
• calculating a time-of-flight of the particle using a time difference between signal pulses received from the at least two collectors;
• pinpointing other signal pulses received from each of the collectors and generated at distinct points in time in accordance with the calculated time-of-flight and relative positions of respective interrogation points corresponding to the collectors;
• and
• associating the other signal pulses to a particle of a different particle set.
