Checking Wavelength Accuracy (XDS)

It is important to check the accuracy of the wavelength peaks using if posible a NIST Standard like in this case.

Manufacturer send a file showing the accuracy of the instrument against this standard and we have to verify periodically to see if it shifts.

The verification tell us if the deviation is more than recommend, even if the diagnostics pass. In this case, we perform an Instrument Calibration and the values come closer to the values from which the instrument leaves the factory.

 

Delta value is the difference between the nominal value and the found value.
