Optical analyzers, optical analysis methods and trained models

摘要

A photoanalysis device includes: an optical system that scans a sample solution to detect light-emitting particles that are scattered in a sample solution and move randomly; a light detection data input part into which light detection data, which is a result of detection of the light-emitting particles by the optical system, is input; a signal processor that generates time-series light intensity data from the light detection data; a concentration calculator that calculates a concentration of the light-emitting particles detected by the optical system, from the time-series light intensity data generated by the signal processor, on the basis of a learned model learned about a relationship between a plurality of time-series light intensity data having different measurement conditions and a concentration of the light-emitting particles; and a concentration output part that outputs a calculation result of the concentration calculator.
