| 1. A method for determining independence of a particulate as a measurement target which is injected into an analysis disc,
said method including:
storing, into a memory, an array of binary data comprising 0s and 1s, which is determined on a basis of a presence or absence
of the particulate and a size of the particulate;
determining the size of the particulate on the basis of the data array in a track direction and a radius direction of the
analysis disc; and
judging that there are plural particulates when it is detected that 1s continue in the data array in the radius direction,
and the number of 1s in the data array in the track direction decreases at least one of a plurality of rows of the data array.
