The Project
Download the Publishable JRP Summary Report
The JRP aims to address the regulatory needs of Raman spectroscopy related to: conventional Raman spectroscopy, tip enhanced Raman scattering, and multi-photon Raman scattering. The JRP will improve measurement reliability, establish traceability, develop reference samples and prepare related documentary standards.
The JRP will make Raman spectroscopy quantifiable by:
- Establishing traceability to the mole by conventional Raman scattering and surface-enhanced Raman scattering (SERS)
- Establishing spatial and depth resolution measurements traceable to the metre (target uncertainty sub micrometre resolution in the XY plane) using Tip Enhanced Raman Scattering (TERS)
- Developing methods for 3D chemical imaging at high speed using multi-photon Raman scattering, Stimulated Raman Scattering (SRS) and Coherent Anti-Stokes Scattering (CARS)
- Investigating light-matter interactions in Raman scattering using finite difference time domain (FDTD) calculations, to establish mathematical models to underpin traceable measurements
- Improving the repeatability of Raman measurements and establishing robust uncertainty budgets for Raman spectroscopy
Impact
The JRP will maximise the impact of scientific developments through close stakeholder engagement. This will ensure the relevance and usability of developed standards. Several activities are planned to effectively disseminate traceability to stakeholders. The following activities are included: Hosting the first metrology session at the seminal International Conference on Raman Spectroscopy (ICORS) meeting in 2012.
- Manufacture and calibration of reference samples suitable as Raman transfer standards
- Inter-laboratory comparisons using the new reference samples, open to the JRP-Partners and stakeholders
- Close cooperation with EN and ISO standardisation bodies to develop relevant underpinning standards
