Hypothesis
The new heating reactor can improve the measurement of urea concentration in biochemical analyses.
Conclusion
The developed flow-type reactor is cost-effective and easy to construct, providing reliable urea measurements.
Supporting Evidence
- When the temperature is set at 32°C, the mean absorbance of the urea standard concentration is 0.051 AU.
- As the temperature increases to 42°C, the mean absorbance rises to 0.135 AU, indicating a positive correlation between temperature and absorbance.
- The reactor is designed for continuous flow analysis in clinical biochemistry and environmental chemistry.
Takeaway
This study created a simple heating device that helps measure urea in liquids quickly and easily.
Methodology
The reactor uses a Peltier-effect heat pump for heating and a temperature sensor for control, measuring absorbance of urea at different temperatures.
Limitations
The reactor's temperature cannot exceed 70°C with the current Peltier modules.
