摘要： An apparatus for separating a component from a liquid is disclosed herein. The apparatus includes a plurality of cartridges disposed within a tank, the cartridges being mounted on a support member rotatable about a first axis, and each cartridge being rotatable about a second axis parallel to the first axis. The cartridges include a plurality of holes on an outer periphery thereof, and contain a supply of a granular ion exchange material capable of separating a desired component from the liquid. Means are provided for transferring liquid to be separated into the tank, and to discharge treated liquid from the cartridges to a location outside the tank.

摘要： One particle group in a sample undergoing measurement is demarcated from another particle group in the sample by drawing a discriminant on a plot of a two-dimensional distribution of the particles. To draw the discriminant, the two-dimensional distribution is divided into a grid pattern of a plurality of areas arranged in a number of columns, the number of particles contained in each area is determined, and an area containing the smallest number of particles is selected from a plurality of areas in a specific column. Next, in a column neighboring the specific column, an area containing the smallest number of particles is selected from those areas adjacent the area selected in the specific column. This operation for the neighboring column is thenceforth successively repeated for all subsequent columns to select the area containing the smallest number of particles in each column. Finally, a representative point is set in each area selected in each column, and an approximation curve is obtained by connecting each of the points. The approximation curve serves as the discriminant.

摘要： A method for demarcating a reticulocyte particle group from a red blood cell particle group in a one-dimensional frequency distribution assumes a normal distribution on one side of the distribution. Various positions Xs.sub.1, Xs.sub.2, . . . , Xs.sub.n, which respectively indicate frequencies that are p.sub.1, p.sub.2, . . . p.sub.n percent (where n is an integer of 3 or greater) of a peak frequency of the distribution, on the normal side of the distribution, are determined. An average value and standard deviation of the normal distribution is determined from these values. A threshold value is next obtained from the average value and standard deviation, the threshold value being used to separate the reticulocyte group from the red blood cell group. The average value and standard deviation may be obtained using a least square method or by computing the mean of several average values and standard deviations.
