Conclusion
The microprocessor system enhances the functionality of NMR spectroscopy by automating signal averaging and purity calculations.
Supporting Evidence
- The digital integrator showed superior performance compared to the conventional capacitive integrator.
- The integration performed by the digital system is not subject to the same leakage and environmental problems as capacitive systems.
- The microprocessor system automates tedious measurements, improving efficiency.
Takeaway
This study created a computer system that helps scientists measure how pure a sample is using special signals from a machine called an NMR spectrometer.
Methodology
The study involved designing a microprocessor system to control an NMR spectrometer and perform signal averaging and purity calculations.
Limitations
The system requires precise settings for accurate measurements and may have errors associated with signal ringing.
