Up until now, the main subject being discussed on this group has been technically called ED-XRF. The ED is for energy dispersive. Specifically simultaneous ED, since the excitation produces a spectrum of electron shell transition energies, from which we derive the individual energy peaks all at the same time with our sensor. There is no reason in the world that an enterprising young amateur scientist couldn't do essentially the same thing manually, using a very simple SCA (single channel analyzer), analyzing the important energy peaks one step at a time.
In this thread we will explore and discuss yet another? manual sequential method called WD-XRF for Wavelength Dispersive-XRF. in which we can analyze crystal structures and have better access to the lowest energy element's identity.
Have fun,
Geo
