Definitions
- the present invention relates to a fluorescent X-ray analysis method and a fluorescent X-ray analysis apparatus, and in particular, at high speed, detects environmental load substances mixed in parts having various compositions constituting electronic equipment and electrical equipment.
- the present invention relates to a fluorescent X-ray analysis method suitable for performing the same.
- the threshold is lOOOppm for Pb, Hg, PBB, PBDE and Cr (VI) and 100ppm for Cd. For this reason, it is indispensable for electrical and electronic equipment manufacturers to confirm that each part does not contain environmentally hazardous substances that exceed regulatory limits.
- a fluorescent X-ray analysis method having a sensitivity of several lOppm and capable of nondestructive measurement is generally adopted.
- the procedure for quantifying the concentration of an element contained in a sample using a fluorescent X-ray analysis method is generally well known. For example, an example is disclosed in Japanese Patent Laid-Open No. 8-43329. ing
- step 301 the voltage and current conditions of the X-ray tube, the quantitative analysis method, etc., and the measurement time t are set.
- the measurement is then started (see step 302).
- step 303 measurement is performed over time t (see step 303), and the measurement is completed (schedule).
- step 304 the concentration of elements contained in the sample is calculated and the accuracy (standard deviation) of the calculation results is calculated to obtain the concentration and accuracy results.
- the density and accuracy results are displayed on a display means such as an LCD and printed out using a printer or the like (see step 306).
- the quantification method as a method for calculating the concentration (that is, the content) of the element contained in the sample is roughly divided into two.
- One is a method (calibration curve method) in which the content of the target element and the spectrum shape are calibrated in advance to create a calibration curve, and the concentration is determined by comparing the shape of the sample spectrum with the calibration curve.
- the other is that all the contained elements are considered to be reflected in the spectrum, and all the contained components are identified from the spectrum and the content of each component is calculated (ie, the total elements in the sample are quantified (total 100%)) (fundamental 'parameter method (FP method)).
- step 301 accurate concentration results cannot be obtained unless measurement conditions are entered correctly.
- the problem (1) is desired to be solved particularly in a situation where it is necessary to quickly analyze a wide variety of parts corresponding to the RoHs directive.
- the determination of the measurement time and the choice of quantification method allows the person performing the analysis to see if the sample is a force ⁇ metal that is made of plastic Alternatively, the judgment is made based on information obtained in advance, and the judgment is made based on this judgment. Determining the type of an unknown sample based on experience requires skill and is not efficient. Especially when the sample is aluminum In the case of light metals such as um or magnesium, it is necessary to quantify the above elements by the calibration curve method.
- misjudgment is a cause of a decrease in the efficiency of the analysis because the sample is measured under improper measurement conditions, resulting in an erroneous result, resulting in confusion and requiring remeasurement.
- misjudgment can be prevented by obtaining information about the sample in advance before measurement.
- the analysis performed after obtaining information in advance is not an unknown sample analysis in a strict sense. Eventually, labor is required to obtain the information and the efficiency of the analysis is reduced.
- the problem (2) will be described with an example.
- Cd content hereinafter also referred to as Cd concentration
- the measurement time t is set at the beginning of the measurement as described above (step in FIG. 3). 301) is carried out.
- an extremely long measurement time t of, for example, 200 seconds in consideration of the possibility of the presence of elements other than Cd.
- this sample is based on plastic, spending 200 seconds of measurement time per sample corresponds to the RoHs directive even though the voltage and current of the X-ray tube can be set high.

- Metallic materials are X-rays for a short time. Irradiation emits fluorescent X-rays with a high spectral intensity, whereas non-metallic materials do not emit X-rays or emit little, except when they contain C or Br. Whether a sample is a non-metallic material or a metallic material can be quickly identified by analyzing the energy and intensity of the spectrum.
- the measurement conditions that can be selected in the above (2) are not limited to only two conditions: a condition for non-metallic materials and a condition for metallic materials.
- a condition for non-metallic materials in addition to whether the sample is a non-metallic material or a metallic material, the type and concentration of the element specifically detected in (1) above are considered.

If it can be determined that the sample is on the order of%, it can be determined that the sample contains C1.
- the calibration curve used for materials containing C1 is not limited to one type, but it is possible to prepare multiple calibration curves with different contents, and select and use an appropriate one from these. It is also possible to virtually create an intermediate calibration curve from the calibration curve for materials containing C1 and the calibration curve for materials not containing C1. is there. The same applies to Br.
