1. A method comprising the steps of:
measuring a signal from a target particle and a reference particle in a cartridge device, wherein
the cartridge device is received into an analyzer to perform the measurement of the signal, and
the signal is measured from the target particle and the reference particle when they flow through a flow cell in the cartridge device;
analyzing the measured signal to obtain signal information of the target particle and signal information of the reference particle; and
determining size information of the target particle by correcting the signal information of the target particle with the signal information of the reference particle.
