This Technical Report describes methods of test that can be applied to wavelength dispersive X-rayfluorescence (WD-XRF) spectrometers to ensure that the spectrometers are functioning in a mannerthat allows precise analyses to be made.The tests outlined are designed to measure the errors associated with the operation of certain parts ofthe spectrometer. They are not designed to check every part of the spectrometer but only those partsthat may be the common sources of error.It is assumed that the performance of the instrument has been optimized according to themanufacturer’s instructions. For all tests, the two-theta angle should be carefully set for the line beingmeasured. The pulse height window should be set according to the manufacturer’s instructions andshould have a broad setting which may also include the escape peak for gas proportional counters. Theinstrument and detector gas environment should be as specified by the manufacturer, as should thepower supply to the instrument.NOTE Where no distinction has been made, it is assumed that a test is applicable to both sequential andsimultaneous spectrometers.
