The proposition has been made and is now gaining popular acceptance that electron energy-loss spectroscopy (EELS) attached to a transmission electron microscope (TEM) can be used to semiquantitatively measure H in minerals-specifically, that there is a pre-peak to the O K edge near 530 eV whose intensity is a measure of H concentration in OH- and H 2 O- bearing minerals.
