Thin film standard

These standards are supplied as fine powders that are dispersed onto holey-carbon films and are selected from the range of certified natural and synthetic compounds already in use by us to prepare bulk analysis standards.The holey-carbon films are supported by a 3.05mm copper grid (400 mesh). However, for analysis under critical conditions, we can supply alternative grid materials, such as beryllium or carbon composite. If requested, we can disperse the standards onto uncoated grids.The standards available at present are:Any selection from 117 Thin Film compound standardsUniversal Set of 25 compound standardsRare Earth SetThin Foil Standards Set for S.T.E.M.
