Abstract
An assay device capable of assaying purity of a substance in an object includes a memory, an emitter, a receiver, a processing unit, and a display device. The memory stores names and standard densities of a number of substances. The emitter emits rays at the object. The receiver receives the rays reflected by the object. The processing unit calculates density of the object according to intensity of the emitted rays and intensity of the reflected rays. The processing unit further calculates purity of a selected substance in the object according to the density of the object and standard density of the selected substance stored in the memory, and outputs the calculated purity to the display device.
