Four independent techniques for quantitatively calibrating an energy dispersive X‐ray fluorescence system are compared. These include commercially available powder standards, vacuum deposited standards, laboratory developed powder standards and a semi‐theoretical method. A technique is presented for using the latter method in the case where the exciting radiation is bremsstrahlung. These methods are discussed and their resulting efficiency values compared. The most complete, most reliable and easiest method is the semi‐theoretical method. Single compound powders of standard chemicals can be used one at a time for periodic checks of the system.
