Web11 de out. de 2009 · The main advantage is the low detection limit. Compared to excitation with an electron beam, excitation with an X-ray source significantly reduces the spectral background and allows trace analysis even in the ppm range. Samples do not have to be coated and penetration depths exceed that of the electron beam by 10 fold. WebBEAM is the filename extension of bytecode compiled from library ( ERL) and header ( HRL) files written in Erlang programming language using BEAM compiler. It can be executed …
