You can buy Highly Oriented Pyrolytic Graphite (HOPG) sheets from PAM-XIAMEN. HOPG is a relatively new form of high purity carbon and provides microscopists with a renewable and smooth surface. Unlike mica, HOPG is completely non-polar, and for samples where elemental analysis will also be done, [...]
