High purity metal substrate discs

EM-Tec high purity metal SEM substrate discs are intended  for X-ray analysis with EDS/WDS or for particle analysis with the SEM.  They are especially useful when standard aluminium or copper alloy SEM stubs generate overlapping background peaks. With the right metal substrate, trace elements in particles can be enhanced through X-ray fluorescence.

EM-Tec high purity metals discs are available in 12mm and 25mm diameter and are compatible with the popular Ø12.5mm and Ø25mm diameter SEM stubs. They can be attached to SEM stubs with carbon tabscarbon paint or silver paint.

  • Available materials are: Ag, Al, Co, Cu, Fe, In, Mg, Mo, Nb, Ni, Pb, Sn and Zn
  • Purity 99.99% or better
  • Sizes are Ø12mm and Ø25 mm, compatible with popular SEM stubs
