(α-β Administration Diagram)
Unmanned operation is possible through the use of The scanner is used to perform qualitative analysis and the 1) Impurity Judgment
The change in analytical values over time can be displayed functions such as a timer to automatically start up the system profiles will be displayed and can be printed out. Compares the unknown sample with standard sample
graphically to enable observation of whether or not analysis and halt it (put it on standby) after analysis is completed. Also, analysis result reports can be created with profile values to judge whether or not it belongs to the same
values have stably entered the specified range. images if the data is combined with a tool like Word Pad. form.
2) Product Type Classification
Registers element standard values and tolerance of
multiple forms to judge what form the unknown
sample is.
3) Form Judgment
Registers the element content range for multiple forms
to judge what form the unknown sample is.
4) Matching Search
Registers the standard values for multiple forms and
searches for a match with the least differences
between unknown sample and standard values.

9 Calibration Curve 10 Matrix Correction 12 Quantitative Analysis Possible using
FP Method
The optimal calibration curve coefficient is calculated by For samples with multiple elements, different measuring
Quantitative analysis is possible with the FP method –
the method of least squares using the standard sample. X-ray intensities will occur depending on the composition
which does not need a standard sample – using the
W = aI 2 + bI + c ratio of the main components, which may cause analysis
scanner and fixed beam monochromators.
W : Element concentration errors. Analysis precision is enhanced if matrix correction is
I : X-ray intensity used.
a, b, c : Calibration constants
As well as being displayed in graph form, the calibration
curve shows the calibration constants, precision and
correlation coefficient, etc.
Graph display size also can be freely expanded and
reduced.
