This invention, a simple and robust method for ammonia detection, offers high-speed in situ quantification of ammonia concentrations with high sensitivity. The ammonia detection system does not require complex instrumentation, analysis, or labeling, which would allow for widespread adoption in chemistry-based fields and surrounding disciplines.
• High-speed, in situ detection of ammonia concentration
• Real-time readings: capacity for fast, real-time chemical characterization in situ.
• Cleanliness: ammonia detection is extremely localized, preventing contamination from environment.
• Reusability: system can be used multiple times.
• Simplicity: Raman substrates are commercially available – would not have to rely on complex manufacturing.
The researchers at the University of California, Irvine invented a surface-enhanced Raman non-contact technique, which operates without having to alter the sample and allows for high speed in situ ammonia detection. Unlike other ammonia tests, this UCI technology offers a reusable approach and minimizes contamination from the environment.
Prototype has been developed and validated for efficacy, achieving a sensitivity of 10 ppm with a 1 second integration time.
