E.M. Separations with High Efficiency of Microgramme Quantities
In the E.M. separation of rare earths it is necessary to convert the commonly occurring rare earth oxides into the more volatile anhydrous chloride form. The material is then transferred to the ion source oven, from which the chloride is evaporated into the ion source. The speed of evaporating is controlled by controlling the oven temperature. This method has proved to be very useful when the amount of material to be separated exceeds 50 mg.
