Go to Beryllium 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. |
