Material Notes:

Advanced Ceramics' graphite monochromators are highly oriented forms of high purity pyrolytic graphite which diffract x-rays and neutrons with greater efficiency than any other material. In x-ray analysis, intensity is increased 3 to 5 times over that obtained with conventionally used crystals. A singly-bent focusing monochromator using graphite yields 3 times the intensity of lithium fluoride at equivalent resolution. GE Advanced Ceramics originally introduced, and still offers, graphite monochromators with the lowest mosaic spread (>= 0.4°) available.Information provided by Momentive Performance Materials, formerly GE Advanced Ceramics.
