Abstract: The Non-Reductive Thermal Ion Emission Characteristics of GraphiteXiao Yingkai (Qinghai Institute of Salt Lakes,Chinese Academy of Sciences,Xining 810008,Qinghai,China)Received Abstract:The non-reductive thermal ion emission characteristics of graphite has been systematically summarized according to the recent publications.The Cs2BO2+,Rb2BO2+,Cs2Cl+ and Cs2Br+ions emited'from Cs2B4O7,Rb2B4O7,CsCl and CsBr respectivelly have been extremely enhanced by coading filament with graphite during load of samples.Using the technique of loading graphite the best precision for isotopic measurements of B,Cl and Br has been achieved.Keywords:graphite,thermal ionization mass spectrometry,boron,chlorine,bromine,isotope
