Potentiometric sensor for anionic surfactant quantification
A high-performance potentiometric sensor platform for the rapid and accurate quantification of anionic surfactants. This technology offers a cost-effective, sensitive, and eco-friendly alternative to traditional titration methods, suitable for quality control in detergent production and environmental wastewater analysis.
Overview
This potentiometric sensor platform provides a precise, rapid, and cost-effective method for the quantification of anionic surfactants in complex matrices. By utilizing custom-designed ion-pair materials as sensing elements, this technology offers a robust alternative to conventional, time-consuming, and waste-intensive analytical methods like two-phase titration or Methylene Blue Active Substances (MBAS) analysis. The platform is designed for high-performance quality control in manufacturing and environmental monitoring applications.
Technical specifications
- High sensitivity with detection limits in the sub-micromolar range.
- Rapid response times, often within 5 to 12 seconds.
- Excellent selectivity and resilience against common inorganic and organic interferences.
- Wide operational pH range, typically spanning pH 2 to 11.
- Proven compatibility with various sample types, including commercial detergents, household care products, and industrial or environmental wastewater effluents.
- Stable signal performance with minimal drift, ensuring reliable end-point detection in potentiometric titrations.
Technology readiness level
This technology is rated at TRL 6. The sensors have been extensively developed, characterized, and validated in academic laboratory settings using real-world commercial samples and industrial effluents. They have demonstrated consistent performance, high recovery rates, and reliability in comparison to standard reference methods, establishing their utility as functional prototypes ready for application-specific optimization or field-testing partnerships.
