This application note provides a detailed method for the validation of the titration method for surfactants. Similar validation can be performed for other developed methods for ensuring the reliability of the acquired data.
Importance of Method Validation
Validation of the analytical method is a prerequisite for maintaining the quality of the production processes as per the regulatory standards. A well-defined and correctly documented validation process serves as evidence for the regulatory agencies stating the suitability of the chemical analysis for its intended use. Parameters such as accuracy, precision, specificity, linearity, detection limit, quantitation limit, range, and robustness are considered while validating the analytical method. The acceptability of the value of these parameters ensures the reliability of the analytical data and for achieving a high-quality end product.
Method Validation for Surfactant Titration by Potentiometry
The application note illustrates the detailed validation of the titration method for surfactants using surfactant sensitive electrodes. The validation parameters are investigated for the determination of anionic surfactant content by potentiometric titration. Surfactant content is generally determined using sophisticated techniques such as chromatography or NIR spectroscopy. However, such techniques are time-consuming, may require long sample preparation and calibration of the instruments, and needs well-trained and skilled operators. Titration analysis with surfactant sensitive electrodes provides a valuable alternative to these analytical techniques since it is less expensive, easier to perform and it does not require a high degree of knowledge from the operators.
