摘要： PURPOSE:To analyze the density of a particle with high accuracy by a method wherein the passage position of the particle is detected, the particle is image-sensed so as to match the timing of the particle which has passed an image-sensing region, its image is analyzed and the number of image-sensed particles is corrected. CONSTITUTION:A particle which does not pass an image-sensing region is not image- sensed, all particles are detected in a detection region and counted by a passed-particle counting device 36. The counting device 36 classifies them according to the position of the particles and the size, and it counts the particles at every classification. As a result, the total number of particles in a sample liquid 6 and the number of particles which have passed the image-sensing region are known. An image-sensed particles counting device 53 counts the particles in an image at every classification analyzed by an image processing device 32. Consequently, the counting device 53 obtains the morphological classification of the particles in the image, and the counting device 36 obtains all the particles and the number of particles in the image-sensing region. Consequently, when a density correction device 39 combines pieces of information and operates them, the total number of particles can be estimated at every morphological classification, and the density of the particles can be estimated with high accuracy.

摘要： PURPOSE:To analyze a large number of samples in a short time with an instrument which analyzes the picture and concentration of particles in urine. CONSTITUTION:A sample is made to flow through a flow cell 1 having an image picking up and particle detecting areas in the form of a flat sheath flow. A sensor 16 actuates a pulsed-light source 2 to emit light upon detecting the passage of particles and takes the still picture of the particles and a picture processor 32 analyzes the kind and number of the particles. A concentration corrector 39 obtains the concentration of the particles by correcting the number of picture-taken particles. Since the sample is analyzed while the sample is made to flow through the flow cell at a high speed, a large number of samples can be analyzed in a short time.

摘要： PURPOSE:To carry out inspections under the optimum condition for an inspecting optical system, by forming the flow of a sample liquid thin, wide and flat, forming a reduced passage at the side of the upstream, forming a parallel flow connected to the reduced passage at a measuring part, and providing a speed reduction passage part after the measuring part. CONSTITUTION:A flow passage of a flow cell 1 comprises a parallel passage part 1a, a reduced passage part 1b, a measuring passage part 1c and a speed reduction passage part 1d. A sample liquid including particles 20 to be inspected running in a direction of an arrow 25 is discharged into the flow passage from a nozzle 3 and becomes a sheath flow surrounded by a sheath liquid from a direction of an arrow 24. The sheath flow flows in the flow cell 1 at a constant speed. The flow is reduced in the thicknesswise direction from a discharge port 19 to a photographing part 21, so that the speed of the flow is increased and at the same time, the flow is stabilized. A sample liquid 23 discharged from the nozzle 3 forms a thin, uniform and flat flow. When the flow is to be photographed by a CCD camera, a focal point is easy to align within a visual field 21 if the flow is flat. Therefore, even a microscope of a small focal depth becomes able to photograph the flow with high accuracy.

摘要： PURPOSE:To improve the inspecting accuracy by forming the flow of a sample liquid thin, wide and flat, forming a reduced passage part on the upstream side and forming a parallel flow connected to the reduced passage part at a measuring part, and providing a speed reduction passage part after the measuring part. CONSTITUTION:A flow passage of a flow cell 1 comprises a parallel passage part 1a, a reduced passage part 1b, a measuring passage part 1c and a speed reduction passage part 1d. A sample liquid including particles 20 to be inspected running in a direction of an arrow 25 is discharged into the passage from a nozzle 3, and becomes a sheath flow surrounded by a sheath liquid from a direction of an arrow 24. The sheath flow flows in the flow cell 1 at a constant speed. The sectional area is reduced only in the thicknesswise direction from a discharge port 19 to a photographing part 21, so that the sheath flow is increased in speed and stabilized. For instance, a stable sample flow 23 of, e.g. 1000mm/sec. or more at high speeds is obtained whereby the photographing accuracy is improved. Moreover, since the sample flow 23 discharged from the nozzle 3 is reduced uniformly in the thicknesswise direction, thereby forming a uniform and flat flow, the photographing accuracy is improved also by this arrangement.
