The Technology
A breakthrough spectroscopy technology
Based on applying Stimulated Raman Scattering (SRS)* in a confined space of Hollow Core Fibers** for a long interaction
This unique nonlinear optical architecture enables implementing SRS spectroscopy with a single laser source
Apply advanced signal processing (RF and digital) to extract high resolution concentration information from the emitted beam in real-time
*SRS spectroscopy – an advanced Raman technique of proven high-resolution, real-time, spectroscopy that never left the Academia
**Hollow Core Fiber – a special structure of an optical fiber that enable gas flow in the hollow region of the optical fiber
Advantages
Technology Competitive Advantages
- A single laser source system
- High dynamic range, from 1 PPM to 100%
- A core system that fits all gases including those that today require special analyzers like H2O, O2 and H2S, and enables the addition of new target gases by simple configuration
- Direct molecular measurement - There is no need for complex spectrum to concentration models that are use in non-Raman spectroscopy technologies and which its updating requires significant maintenance efforts
- Measurement is not affected by humidity compared to other spectroscopy technologies where humidity removal prior to measurement is a must
- Simplified Microfluidic gas sampling subsystem
- Small size, can be lower than 30 litter in volume
- Significantly small sampling volume tens of ml/H vs hundreds of litters/Hr
- A basic core analyzer that can replace multiple analysis techniques ( GC, FTIR , TDLAS , GFC-NDR, UV and more
