PROBLEM TO BE SOLVED: To provide a material classification apparatus and method, which have a simple constitution, and enable a size classification with a high precision. SOLUTION: A passage 2 becoming gradually shallower toward the downstream side while inclining the bottom is formed on a glass plate (passage substrate) 1. A cover glass 3 covers so as to occlude a part of the passage 2 in the passage direction. Scale marks m1-m5are attached to the cover glass 3 at a predetermined interval along the passage. When a sample solution is flowed from the upstream side end (passage starting edge 2b) of the passage 2, a collection is carried out from what has a big size in turn, and the collection of what has a smaller size is carried out at the downstream side. The size of the collected material s can be discriminated from the scale mark of the cover glass 3. COPYRIGHT: (C)2008,JPO&INPIT
