Beryllium Support Film, 25x25 mm, Each

Details:

A deposition of 250 angstroms thick beryllium onto the 0.005" Thick, 25x25 mm squares of a cu substrate. The be can be removed by dissolving the substrate in nitric acid (50:50). The be film will then be removed from the acid, washed in distilled water and mounted on tem grids. A be support film will reduce background interference to a minimum and it is particularly useful where analyses for c or si are required, so that these alternative supports cannot be used. Another advantage of the be support is its very fine grain size which produces a very sharp ring pattern for in-situ calibration.
