Abstract
An epoxy resin-based embedding media doped with a non-conductive dopant to a predetermined w/w % such that the media is non-charging at 1.8 keV. A preferred dopant is polyethylene glycol at a molecular weight of at least 3350, and having a predetermined w/w % is at least 2% and up to 20%, most preferably from 2% to 10%. Another preferred dopant is polyethylene glycol at a molecular weight of 7000-8000 and a predetermined w/w % of up to ˜40% and more preferably of up to ˜30%.
