Non-Contact 3D Surface Metrology of Large Grain High Purity Niobium by SLCM and FESEM
of the surface. topology at the grain boundary. Because the soft high purity Nb is easily damaged, and each sample. must undergo multiple characterization tests, a non-contact measurement technique must be used to. quantify the local topology. In this study we compare surface height measurements from 1

USP Tests to be Updated
We could design tests that would guarantee the purity and identity of every material known to man. We could do that. The cost would be prohibitive and everybody would have to have a 900 megahertz NMR and the latest, greatest mass spec and the best density equipment, and it would be... Some
