Overview
This innovative solution leverages Raman spectroscopy to rapidly and non-destructively quantify the degree of hydrolysis in organo-trialkoxysilane solutions. By employing a chemometric model, this technology converts Raman spectra into a quantitative hydrolysis index, facilitating at-line quality control. The process is fully automated, requiring no sample preparation, and delivers results in under 5 minutes, making it a reliable, efficient, and user-friendly tool for industrial applications.
Technical specifications
- Utilizes a 785 or 1064 nm Raman spectrometer in free-space or immersion probe configuration.
- Tracks changes in silicon center integrity through three vibrational markers: Si–O–C stretch (600–750 cm⁻¹), Si–O–Si stretch (450–550 cm⁻¹), and alcohol peaks.
- Chemometric model calibrated against ²⁹Si NMR-confirmed samples for accurate hydrolysis measurement.
- Automated analysis provides a hydrolysis index without spectral interpretation.
Technology readiness level
This technology is currently at a TRL 4, having undergone initial validation phases. Future phases include instrument integration, validation against blind samples, and industrial handover to ensure readiness for practical deployment.
