Abstract
There is provided a dissolution properties measurement system using a piezoelectric sensor, capable of continuously measuring dissolution properties of a substrate in an aqueous solution by using the piezoelectric sensor. The dissolution properties measurement system includes: a specimen receiving unit including a chamber receiving a specimen therein; a mass measuring unit connected with the specimen to measure a mass change of the specimen in real time; and a dissolution properties measuring unit measuring a dissolution properties of the specimen on the basis of the value measured by the mass measuring unit.
