Geo-Raman, Nancy, FR (Report)

20th June 2012

The Geo-Raman Xth Meeting was held in Nancy from June 11-13; over 50 presentations and close to 100 poster sessions were attended by more than 130 participants from around the world. The conference covered Raman spectroscopy applied to Earth Sciences and demonstrated the rapid developement of this technology in numerous applications.(see program at http://georaman10.uhp-nancy.fr/georaman/Conference%20Program7JUIN.pdf).

From 3D Raman using imaging systems costing $100k+ to suggestions of UV gated Raman reducing luminescense by a factor of 100 which caught many participants by surprise. The instrument shows the typical Raman diamond feature only for type IIa; it would be an ideal instrument for CVD detection. However, the parts need to be UV capable and a 244nm pulsed laser still
costs $ 20,000.

Gemlab Research & Technology submitted an abstract and a poster(download http://www.cigem.ca/research/GeoRamanPoster.pdf 950KB, PDF) �The GL Gem Raman � a powerful tool in gem and mineral identification�.

Raman spectroscopy is an ideal technology for gems and mineral identification. The GL Gem Raman quickly can tell the difference between diamond, cubic zirconia, glass and zircon, distinguish jadeite from nephrite, separate real from faux pearls, tell whether it is ivory or plastic; it works great on beads, carvings and gem materials set in jewellery.
