Hypothesis
Can a modular motion control system improve the automation of the McBain-Bakr balance for measuring adsorption isotherms?
Conclusion
The developed motion control system successfully automates the measurement of adsorption/desorption dynamics using the McBain-Bakr technique.
Supporting Evidence
- The robot was able to accurately measure the elongation of a spring due to gas adsorption.
- The automation system improved data collection speed and reliability compared to traditional methods.
- Initial and final measurements taken by the robot closely matched those obtained using a cathetometer.
Takeaway
This study created a robot that helps measure how gases stick to surfaces, making it easier and faster to collect data.
Methodology
A microcontroller-based stepper motor driver was developed to automate the McBain-Bakr balance for measuring adsorption isotherms.
Limitations
The study acknowledges potential noise from the industrial environment affecting measurements.
