Graphite monochromator
WebFor X-ray investigations, a few drops of each sample of interest (FFF fractions 1, 2) were deposited onto a recessed silicon glass and allowed to dry. X-ray powder diffraction analyses were carried out by means of a Philips X’Celerator powder diffractometer equipped with a graphite monochromator in the diffracted beam.
