Definitions
- Procedures for quantifying the concentration of element contained in a sample using this type of analysis method are generally well known. A method as an example will be described with reference to FIG. 11 (see Patent Document 1).
- the present invention has been made in view of the above problems that have been found based on the experiments of the inventor, and an object of the present invention is to provide a fluorescent X-ray analysis method and a fluorescent X-ray capable of shortening measurement time and improving operability.
- An object of the present invention is to provide a line analyzer.
- the fluorescent X-ray analysis method is a fluorescent X-ray analysis method for analyzing constituent elements of a fluorescent X-ray force sample generated from a sample irradiated with X-rays, the setting step, It comprises a measuring step, a deriving step, an ending step, and an output step.
- the setting step sets the measurement conditions of the sample.
- the fluorescent X-ray is measured.
- the deriving step derives the measurement concentration and measurement accuracy of the constituent elements from the measurement result.
- the end step ends the measurement of the fluorescent X-ray when the measurement accuracy satisfies the measurement conditions.
- the output step outputs the measured concentration or the measurement accuracy.
- ⁇ 1 is the value of the upper limit target value set in step 121
- kl is the value of the accuracy coefficient set in step 121. That is, when it is determined that the measurement accuracy of the calculation result in the calculation unit 202 is less than the set value ( ⁇ lZkl), the process proceeds to step 126, and the measurement ends (see step 126). .
- the ending condition is indicated using an inequality sign ( ⁇ ) in the expression (3 ′), the part may be an inequality sign [equal sign] ( ⁇ ).
- Each judgment result is displayed by a symbol or the like.
- the judgment result is displayed as ⁇ ⁇ '' when the measurement concentration X satisfies X ⁇ Xtl, ⁇ ⁇ '' when Xtl ⁇ X ⁇ Xt2 is satisfied, and ⁇ X '' when Xt2 ⁇ X ⁇ Xt2 is satisfied. It is done by doing.
- measurement accuracy ⁇ X if the measurement accuracy ⁇ ⁇ ⁇ satisfies ⁇ ⁇ atl, “ ⁇ ”, if ⁇ tl ⁇ ⁇ ⁇ t23 ⁇ 4- This is done by displaying “X” when ⁇ ⁇ ⁇ is satisfied.
- the display of the judgment result is not limited to this, and any display may be used. However, it is preferable that the display be a display that is easy for the user to recognize.
- the set value a which is the smaller value of ( ⁇ lZkl) and ( ⁇ 2 / k2), and the measurement accuracy ⁇ X is determined, and measurement is performed until a stricter one of the measurement conditions set in step 141a is satisfied.
