Abstract
A sequential X-ray fluorescence spectrometer according to the present invention includes a total analysis time display unit configured to measure, for each kind of analytical sample, a standard sample which contains a component at a known content as a standard value to determine a measured intensity of each measurement line corresponding to the component. The total analysis time display unit is further configured to calculate, for each component, a counting time which gives a specified analytical precision by using the standard value and the measured intensity and to calculate a total counting time as a sum of the counting times of respective components. The total analysis time display unit is configured to calculate a total analysis time as a sum of the total counting time and a total non-counting time and to output the calculated total analysis time and the calculated counting times of the respective components.
