Chemical Analysis Using Titration TRIZ Cases
- Water Alkalinity Detection Using pH Sensing and Air Injection
Automated pH sensing and air injection calculate KH without titration reagents, reducing water waste and manual aquarium testing.
- BDD Electrode Stirring for Small-Volume Alkalinity Titration
A boron-doped diamond electrode lets a stir bar contact the cell surface directly, improving small-volume alkalinity titration speed and accuracy.
- COD Reagent Composition for High-Chloride Water Measurement
Mercuric sulfate and potassium aluminum sulfate suppress chloride interference, enabling direct COD measurement up to 20,000 mg/L without dilution.
