Researchers at Purdue University have developed a new optical Raman spectroscopy system. Current Raman spectroscopy techniques are not suited for large spatial scales and field - relevant chemical concentrations. The Purdue technology enables Raman analysis at multiple spatially-dispersed locations using a single source-detector unit, facilitating long-term, spatially dispersed monitoring and enabling low cost-per-test-point sensing. This invention has applications to sensing of environmentally- and industrially-relevant compounds, particularly when analysis/monitoring is required at multiple points or over large spatial extent.

Technology Validation: In a series of tests, Raman analysis was successfully carried out from a single source and detector unit to examine test points 1 to 16 m from the unit. Modelling of instrument performance demonstrates the potential to reach 1000-2000 m at field-/industrially-relevant concentrations.

Advantages
- single detector
- long-term
- spatially-dispersed analysis

Applications
- sensing of environmentally-, industrially-relevant compounds
