Carbon planchets

Carbon (graphite) planchets are ideal substrates for backscattered electron imaging in a SEM. The spectroscopically pure carbon discs provides an excellent conductive, low emission X-ray background free of any characteristic X-ray peaks except carbon. Carbon planchets are preferred over the non-conductive diamond planchets (charging will have negative effects on the analytical results and can distort X-ray mapping and imaging).For fine powders and imaging applications, vitreous carbon planchets are 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.Spectroscopically pure carbon Grade 1 (graph...

Carbon (graphite) planchets are ideal substrates for backscattered electron imaging in a SEM. The spectroscopically pure carbon discs provides an excellent conductive, low emission X-ray background free of any characteristic X-ray peaks except carbon. Carbon planchets are preferred over the non-conductive diamond planchets (charging will have negative effects on the analytical results and can distort X-ray mapping and imaging).

For fine powders and imaging applications, vitreous carbon planchets are 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.

Spectroscopically pure carbon Grade 1 (graphite) planchets with total impurities equal to or less than 2ppm with each single element 1ppm or less. Trace elements can be Si, Al, Fe, Mg, Ca or B. The carbon discs have a fine ground finish on one side; 0.80µm (32µ inches). All carbon planchets are 1.6mm (1/16") thick. Sizes from 10 to 32mm diameter to fit all styles of SEM pin and cylinder mounts varying from 10 to 32mm diameter.

The carbon planchets can be cleaned and used again.
