XCS EDS/BSD calibration standard

The XCS EDS calibration standards are practical, high quality and compact EDS calibration standards using a standard type 12.7mm pin stub as retainer. The small size of the pin stub allows for using the XCS calibration standard alongside specimens on readily available multi pin stub holders. This enables quick in-situ calibration and regular performance tests of the EDS system, Back Scattered Electron Detector and light element detection performance of the EDS detector. The pure elements and compounds are mounted in the 12.7mm stubs using a highly conductive silver epoxy. All XCS calibration standards are carbon coated for improved conductivity. The XCS EDS calibration standards are available in 6 fixed configurations:

SXCS-5 is intended for EDS calibration and contains ANSI 316 stainless steel, SiO2, Mn, B, C and a 200um Cu aperture grid in a 12.7mm aluminium pin stub.

Each XCS EDS X-ray calibration standard comes with a certificate issued by the manufacturer stating the purity and origin of the elements, compounds or alloys. The ANSI 316 stainless steel is NBS SRM 1155 (standard reference material) which is traceable to NIST. The other elements, compounds or alloys are not NIST traceable.
