A set of six standards plus a 150µm Molybdenum Faraday cup mounted in a 25mm diameter x 5mm block, designed to provide a wide range of calibrations and performance checks.
The six standards BN, C, Mn, Co, Cu and Spessatine Garnet (Mn3Al2Si3O12) can be used for determining energy scale calibration, detector resolution, light element sensitivity and resolution, thin window contamination and probe current stability.
