The results of the first international comparison of the measurement of graphene have been published in 2D Materials, led by NPL, through the Versailles Project on Advanced Materials and Standards (VAMAS) and in collaboration with institutes from around the world.
The international interlaboratory comparison (ILC) outlined improvements that reduce measurement uncertainty, in some cases by a factor of 15, and which will be the basis for a new international standard which is currently under development within ISO/IEC for Raman spectroscopy. This will provide a verified source of data and ultimately provide more accurate and precise measurement standards for the global graphene industry.
