You'd get a hell of a lot better resolution with an e-beam blowing up nanometer-sized spots, and feeding the ejecta thru a mass spectrometer. See my talk a couple of years back at Alcor. But I would suggest that this is *waaaay* off-topic for this list... uploading implications to the contrary notwithstanding.
