Calibration of the energy-dispersive x-ray fluorescence spectrometer with Cd-109 annular excitation source is discussed. Experiments were performed to calibrate such a spectrometer using both thick standards and one type of commercially available, thin, single-element standard. It was found that the use of thick standards in such calibrations is reliable and accurate, in addition to being inexpensive and readily available.
