Raman Spectroscopy vs. XRF sounds like the next UFC event. Seriously though, does anyone know which of the two is more accurate? Or do they measure different properties? I have access to an XRF analyzer but are there any universities or commercial services that offer Raman Spectroscopy besides SGL? The top of the line GemmoRaman-532SG found here will set you back almost $22K. Definitely a tool for the full time professional at that price. While a handheld XFR analyzer like this one is only a cool $40K. The advantage of Raman Spectroscopy seems to be you can compare results from an online database while the XRF is portable. Just curious.

You can find handheld XRF for around $10,000. Seen some on Ebay in the past in the $6,000 range.

The only thing about eBay (and Wal-Mart) that doesn't surprise me is that you can't buy a $3 Chinese pacemaker. The less expensive portable XRF units are not designed or intended for geochemical analysis and read a few number of elements.
