Hypothesis
The study aims to develop a microcomputer-controlled electrode switch for potentiometric determinations.
Conclusion
The developed electrode switch is inexpensive, easy to assemble, and compatible with most potentiometric systems.
Supporting Evidence
- The electrode switch can be easily built from available materials and costs approximately $20.
- It allows for sequential determinations with several ion-selective electrodes.
- The device is compatible with most automatic potentiometric systems.
Takeaway
This study created a device that helps measure different chemicals automatically, making lab work easier and faster.
Methodology
The electrode switch was constructed using a microcomputer, a pH meter, and a digital burette, with a focus on noise immunity and signal processing.
Limitations
The study does not address the performance of the switch in all possible laboratory conditions.
