    • PROBLEM TO BE SOLVED: To solve a problem wherein, a conventional flow-type particle analysis device is unable to detect both an artificial error such as leaving a sample behind, shortage of the sample or shortage of a reagent and a failure of a channel system, by an inexpensive and simple system.
      SOLUTION: The analysis device includes: an image processing means for calculating RGB density distribution information of the whole image in each image, in parallel with normal image processing for performing classification processing of object particles, in image processing of a photographed image obtained during measurement of the sample; a failure state determination processing means for determining whether an image photographed based on a tendency of the RGB density distribution is in an abnormal state or not; and a failure determination processing means for calculating an appearance frequency of an abnormal image when whole measurement to one sample is finished, and finally determining presence/absence of a failure. Consequently, failure diagnosis in parallel with normal analysis can be performed without changing a conventional device constitution.
