The newly released SPI Boron Carbide Specimen consists of boron carbide
particles dispersed on a carbon supported copper grid, 200 mesh, and as is
clear from the micrograph above, it forms an easy-to-use test specimen for
determining and calibrating the energy resolution of wavelength dispersive or
windowless energy dispersive x-ray spectrometers interfaced to a TEM. The
values for the emission peaks for B and C are, respectively, 0.185 and 0.282
KeV respectively.
Note: The SPI product was fashioned from the boron carbon test specimen
found at one time, in the consumables of what was once Polaron Equipment Ltd.
Indeed, we believe this new SPI boron carbide specimen would be indistinguishable
from the original Polaron made product.
