Abstract:
1. A fine particle measuring method for performing optical measurement of fine particles introduced into a plurality of sample fluidic channels provided at predetermined equal distances on a substrate by scanning a measurement light to the plurality of sample fluidic channels, the method comprising the steps of: sequentially irradiating the measurement light to at least two or more reference regions provided on the substrate on one or two outer sides of the plurality of sample fluidic channels; detecting a change of an optical property occurring in the measurement light due to the reference regions; calculating a time for emitting the measurement light to each of the plurality of sample fluidic channels respectively on the basis of a time difference between a detection time of a change of the optical property caused by one of the at least two or more reference regions and a detection time of a change of the optical property caused by another one of the at least two or more reference regions and a total number of the plurality of sample fluidic channels; scanning the measurement light to each of the plurality of sample fluidic channels at the calculated respective time, wherein a light is generated from a fine particle in each of the plurality of sample fluidic channels; converting the light generated from the fine particle into an electric signal; and analyzing an optical property of the fine particle based on the electric signal to output a measurement result.
