The EM-Tec CXS-5F calibration standard includes 5 reference materials and a 200µm aperture copper Faraday cup. All mounted in a compact Ø12.7mm standard aluminum pin stub. The copper Faraday cup and aluminum pin stub can serve as a Cu/Al reference for detector gain/zero calibration. Intended for: EDS detector performance, light element detection, EDS detector resolution, EDS detector calibration and quantitative analysis test. Similar to #36-00505; EM-Tec CXS-5F, but with BN instead of B to add N.Reference materials: Stainless steel (SRM 1155), Sio2, Mn, BN and C. 200µm copper Faraday cup.
