dNot sure how you would actually separate the electrons from the nuclei. In an Inductively coupled plasma analyzer, a sample is inductively heated to the point of ionizing the elements of the sample. But in a plasma, the electrons are still there. Basically it is electro-neutral since each element is still present, just not connected, so to speak. One of the keys of this instrument is the electromagnet that does the inducing. The effect is heat and ionization, but not much else. Anything beyond that and I am speculating.
