DISSOLUTION TESTING WITH INFRARED TEMPERATURE MEASUREMENT
First Claim
1. A dissolution test apparatus, comprising:
- a vessel support member comprising a plurality of vessel mounting sites for supporting a plurality of vessels, each vessel mounting site having an aperture for receiving a vessel;
a sensor support member disposed proximate to the vessel mounting sites;
a plurality of infrared temperature sensors mounted at the sensor support member, each infrared temperature sensor positioned proximate to a respective vessel mounting site to receive infrared radiation emitted by media contained in a vessel mounted at the aperture, and configured to transmit a measurement signal indicative of the temperature of the media; and
an electronic controller communicating with the plurality of infrared temperature sensors and configured to receive and process the measurement signals transmitted from the infrared temperature sensors.

Abstract
A dissolution test apparatus may include a vessel support member, a sensor support member, infrared temperature sensors, and an electronic controller. The vessel support member may have apertures for receiving vessels. The infrared temperature sensors are mounted at the sensor support member. Each infrared temperature sensor is positioned proximate to a respective vessel mounting site to receive infrared radiation emitted by media contained in a vessel mounted at the vessel mounting site, and is configured to transmit a measurement signal indicative of the temperature of the media. The electronic controller communicates with the infrared temperature sensors and is configured to receive and process the measurement signals transmitted from the infrared temperature sensors. The electronic controller may be configured to control media temperature in the vessels.

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20)
