A method of performing, and an apparatus for dissolution analysis on a pharmaceutical tablet. The method comprising irradiating a tablet with radiation having at least one frequency in the range from 40GHz to 100Thz, detecting radiation which has been transmitted through or reflected by the tablet, determining a parameter from the detected radiation indicative of the density of a coating layer of the tablet; and determining information about the dissolution characteristics of the tablet from said parameter. The parameter indicative of the density may be the thickness of the coating or time of flight of the radiation through the tablet coating. The detected radiation may be the maximum signal strength reflected by the tablet. |
