Dissolution testing with infrared temperature measurement

A method for measuring temperature of dissolution media contained in respective vessels of a dissolution test apparatus, the method comprising:

• inserting a plurality of vessels through respective apertures of a vessel support member of the dissolution test apparatus;
• positioning a sensor support member proximate to the vessels such that a plurality of infrared temperature sensors supported by the sensor support member are positioned proximate to respective interiors of the vessels without being submerged in volumes of dissolution media respectively contained in the vessels;
• heating the respective volumes of dissolution media;
• and
• non-invasively monitoring the temperatures of the respective volumes of dissolution media by operating the infrared temperature sensors to receive infrared radiation emitted from the respective volumes of dissolution media, generating measurement signals indicative of the temperatures of the respective volumes of dissolution media, and transmitting the measurement signals to an electronic controller of the dissolution test apparatus.
