Vitreous Carbon and Carbon Planchets

Vitreous carbon and carbon (graphite) planchets are ideal substrates for X-ray analysis and backscattered electron imaging in a SEM or electron microprobe. The spectroscopically pure carbon provides an excellent conductive, low emission X-ray background free of any characteristic X-ray peaks except carbon. Carbon planchets are favored over the non-conductive diamond planchets (charging will have negative effects on the analytical results and can distort X-ray mapping and imaging).
The carbon planchets can be cleaned and used again. For fine powders and imaging applications the vitreous carbon is the best choice. For X-ray applications of larger particles or specimens or for applications where the planchets can not be used again, the carbon (graphite) planchets are adequate.

vitreous carbon (graphite) planchet

Vitreous Carbon Planchet

Mirror Finish, One Side

Polished surface for extreme smoothness, sometimes called "glassy" carbon. For analytical work, X-ray investigations.

Impermeable to gases and liquids, high purity, corrosion resistant, thermal stability in air up to 550°C and in vacuum or inert gas up to 3,000°C. Very hard and strong. Applications in the fields of chemical analysis, metallurgy, crystal growth, medical technology and in glass and ceramics research. MSDS

Upon request a typical chemical analysis of this vitreous carbon will be supplied. ("MF" = Mirror Finish).
