This survey is intended for any users of Raman spectroscopy. The purpose of the survey is to identify challenges in reproducibility (i.e. from one lab to another, from one day to another, or reproducing a report or publication) and their relative importance to the community of users of Raman spectroscopy. 

The results of this survey will be used to prioritize future work on standardization in Raman Spectroscopy, for example by National Measurement Institutes (NMIs), international standards organizations, and by others.

The results of the Survey are planned to be posted on the Versailles Project on Advanced Materials and Standards (VAMAS) website under Technical Working Area (TWA) 42: Raman Spectroscopy and Microscopy.  Further information is available at http://www.vamas.org/twa42/index.html .

Please share this survey with fellow users of Raman spectroscopy.
