Abstract
An anode target comprises a copper block having different elemental target materials bonded to segments of the circumference, which rotate past the electron emitting cathode, to provide different emission lines in sequence. Aluminum and silicon target materials produce lines which bracket the aluminum absorption edge, to detect small amounts of aluminum in the presence of other absorbing materials by differential absorption of these two lines. Silver and rhodium may be used to bracket the chlorine absorption edge.
