| Abstract: | The selenium plays an important role in human health. The importance of trace selenium element analysis has been recognized by more and more people. This paper refers to the measurement of natural selenium isotope by negative thermal ionization mass spectrometry. The silica gel and Ba(NO3)2 were respectively deposited on evaporation filament and ionization filament. We have achieved a little advance in this experiment. |
