| Abstract: | Magnesium is precipitated as hydroxide after elimination of interfering elements by means of ion-exchange procedures (phosphate, iron, trace elements) and masking with EDTA (calcium). The sample is applied in form of MgCl2 to the tungsten filament of an 1-filament-ion-source for surface ionization. |
