摘要： There is disclosed an apparatus for the determination of a trace amount of an analyte substance or organism. A substrate solution is brought into contact with a small diameter tube which has captured, at least on its inner surface, a trace amount of an analyte substance or organism. The trace amount has the ability to change the pH of the substrate solution. A pH change following a reaction of a substrate in the substrate solution in the small diameter tube is measured; the apparatus has a cuvette having an inlet and an outlet for the substrate solution, a pH electrode accomodated in the cuvette, a pump for supplying the substrate solution in the cuvette, a positioning structure for positioning, in the cuvette, the small diameter tube with the pH sensitive plane of the pH electrode and spacing the surface and the plane at 1 mm or below from each other, and a sealing structure for maintaining a formed by the outer surface of the small diameter tube accommodated in the cuvette and the inner surface of the cuvette at liquid tight condition.
