Abstract

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;
