Conductivity Measurement of Citrate Solutions by Titration
Conductivity measurement of citrate-containing solutions can be performed using titration with photometric endpoint detection. This approach provides a reliable and repeatable method for routine quality control in laboratory and production environments.
⚙️ Analytical Principle
The method is based on titration with calcium chloride (CaCl2) to form calcium carbonate, resulting in a measurable change in solution clarity.
- Endpoint detection using photometric measurement
- F-cross detection identifies turbidity change
- Automated titration improves repeatability
⚙️ Measurement Workflow
- Sample collection
- Add Na2CO3 and NaOH
- Titrate with CaCl2
- Automatic endpoint detection
The procedure is simple and supports consistent measurement across multiple samples.
📊 Performance
- Stable and repeatable endpoint detection
- Photometric unit enhances precision
- Suitable for routine QC measurements
The use of automated titration reduces operator variability and improves measurement consistency.
⚙️ Instrumentation
Measurements can be performed using Hiranuma auto-titrators equipped with a photometric unit (M-3000).
