Prototype Titration Calorimeter for Physical and Analytical Chemistry Laboratories
The physical chemistry laboratory at BYU wants to use an inexpensive and user friendly titration calorimeter for students to learn how to do calorimetric measurements. This calorimeter is designed so that students can readily observe the operation and reaction conditions along with simultaneous electrochemical and spectroscopic measurements. Software and electronics are designed and implemented into the calorimeter to provide the necessary controls to achieve and record the desired outputs of the system. A Proportional Integral Derivative (PID) algorithm is implemented on an Arduino microcontroller to provide a stable temperature for accurate measurements. Motors for stirring and buret drive are also controlled by the Arduino system. Data is retrieved from multiple sensors and stored for analysis after each reaction. A prototype calorimeter has been built, but research and development is in progress to improve the system and its functions.
