4) Procedure

1. Method Development Objectives:
   1. Define objectives for developing titration methods based on regulatory requirements and product specifications.
   2. Identify appropriate titration technique (e.g., acid-base, complexometric) based on analyte properties and titrant characteristics.
2. Selection of Titration Technique:
   1. Evaluate and select appropriate titration technique based on analyte concentration range, titrant stability, and endpoint determination.
   2. Consider method accuracy, precision, and robustness.
3. Optimization of Method Parameters:
   1. Optimize titration method parameters such as titrant concentration, indicator choice, and endpoint detection method.
   2. Perform titration method validation to ensure method performance meets predefined criteria.
4. Validation of Titration Methods:
   1. Validate titration methods according to regulatory guidelines and predefined acceptance criteria.
   2. Document validation results and conclusions regarding method suitability for analyte quantification.
5. Documentation and Reporting:
   1. Document all titration method development activities, including method objectives, technique selection, optimization, and validation.
