MAC X-ray Fluorescence Standards, Electron Microscopy Sciences

MAC X-ray Microanalysis standards are supplied as 33 m (¹/₄") diameter pressed pellets or metal foils, and are prepared from selected high purity elements and compounds to ensure interference free-spectra. They are suitable for use by experienced spectroscopists as well as staff training.

Each of the pressed pellets is supported by a thin-walled aluminum cup which is protected from damage during handling and minimizes the risk of touching the standard materials, some of which are harmful
