analysis will affect other elements test. Besides, some elements oxide will cause othe
r elements test deviation. Under many condition, this deviation is very small, even the
results without calibration are accurate enough, especially for the tests purely for obs
erving which elements included. If more accurate data are required, then TrueX equip
ment supply the slope/intercept user concerned elements can do calibration automatic
ally to improve data quality. It can calibrate single elements also mutiple elements. Th
e calibration factors are independent, so will not affect each other mutually.
Before regular test, you should first set deviation allowage scope. And use other
methor, e.g.laboratory method to do the sample test, then use TrueX analyzer to meas
ure. If the result already meets application demand, then the device does not need to c
alibrate. If calibration is essential, then you need to establish calibration factor. The lo
cal landscape feature changing requires re-check results whether they are in the scope
of allowed deviation.
2.4.1 Process for establishing correction factors
Establishing correction factors need to be measured at least 5 sample.(The more
the sample, the better, If it is not enough, there are no less than three
），
The concerned
elements must have a gradient in the content. Increasing the number of measured
samples can increase the accuracy of the measurement.
The basic procedure to establish the correction factors are as follows:
1. Select Factory-Default factor
2. The samples were measured for at least 80 seconds.
3. The correction factor is determined by the sample of known content
。
4. Create a new model, In the new model, Put the correction factor into element
corresponding item
5. Select the new model as default model.
2.4.2 Calculating a correction factor
For each element, For each element, we have drawn on the figure below standard
content ratio (by mass fraction representation)
