SPI Diamond Grids

Comparision of Bremsstrahlung radiation levels for SPI diamond
vs. SPI beryllium TEM grids


The levels of Bremsstrahlung background radiation, especially for EDS studies, if of great importance to the analyst because elevated levels can erode quickly the sensitivity of the final data.  The carbon in carbon mounts has typically been associated with high background radiation levels and beryllium has always been associated with low background levels

The use of beryllium grids and/or planchets has in the past been popular because of the low Bremsstrahlung background radiation levels, in comparision to the alternatives.  The purpose of this data is to show that one can get comparably low Bremsstrahlung background radiation levels with diamond grids as with beryllium grids.
