Laser absorption spectroscopy for hydrolysis quantification
A laser-based absorption spectroscopy method for non-destructive, rapid assessment of hydrolysis in organo-trialkoxysilanes, leveraging a tunable diode laser for high-resolution measurements. Ideal for industrial applications due to its precision and ease of integration.
Overview
This solution introduces a laser-based absorption spectroscopy technique to quantify the degree of hydrolysis in organo-trialkoxysilanes, offering a non-destructive and rapid assessment. By utilizing a narrow-linewidth, tunable diode laser, this method detects subtle changes in electronic absorption characteristics, enabling precise measurement of the evolving silane system. This approach is particularly suited for industrial environments, providing rapid analysis and seamless integration into existing workflows.
Technical specifications
- Utilizes a continuous-wave tunable diode laser operating at 393–395.5 nm for high-resolution absorption measurements.
- Designed with a sealed liquid sample chamber to ensure reproducibility and minimize environmental perturbations like moisture ingress.
- High spectral resolution and narrow linewidth allow detection of minute spectral changes, outperforming broadband techniques.
- Achieves high signal-to-noise ratio through coherent and stable illumination.
Technology readiness level
This technology is currently at TRL 2, indicating that it is in the early stages of experimental proof-of-concept. The solution is undergoing a phased feasibility and development plan, with future phases focused on calibration, validation, and refinement for at-line industrial application.
