These images were collected
using the Gatan Image Filter on the JEOL 2010F TEM/STEM from
a BN sample dispersed on a holey carbon film. The electron
energy loss spectrum shows families of peaks for B, C, and
N in order of increasing energy loss (upper left). The images
at the upper right and lower left are EFTEM maps for B and
C, respectively. The image on the lower right represents
a combined map for B (blue) and C (yellow).
