摘要： An analyzer for analyzing urine material components is provided, which comprises: a sheath flow cell for forming a sample stream by surrounding a sample liquid containing preliminarily stained particles of the urine material components with a sheath fluid; a light source for illuminating the sample stream; a photodetecter section for detecting optical information from the illuminated material component particles; and an analyzing section for analyzing the material components on the basis of the detected optical information; the analyzing section including a parameter extracting section for extracting a fluorescent light emission duration Flw and a scatter light emission duration Fscw as parameters from the detected optical information, a distribution diagram generating section for generating an Fscw-Flw scattergram, and a judging section for judging whether or not a material component particle being analyzed is a cast, on the basis of location of a data point of the material component particle in the generated scattergram.
