摘要： The purpose of the present invention is to provide a simple measurement tool which can rapidly measure various chemical substances contained in environments or from inside a living body by a simple or inexpensive means/method.The present inventions relate to, for example, a simple measurement tool for test substances comprising: at least two reaction regions, each composed of a water-based liquid, the reaction regions being independent of each other; boundary region(s) composed of a gel-type substance that is not or hardly soluble in the water-based liquid; a container holding the reaction regions and the boundary region(s); and magnetic particles carrying a reactive substance immobilized on a surface thereof, in which: the reaction regions are separated from each other via the boundary region(s); and by using external magnetic field-applying means, the magnetic particles can be substantially exclusively transferred from one reaction region to another reaction region through the boundary region separating these reaction regions, while independence of the respective reaction regions and the respective boundary regions and a function of the magnetic particles being maintained.
