We have developed charged particle activation analysis to determine light elements at a sub-ppb level. This analytical method is characterized by sample bombardment with charged particles at a few tens of mA and substoichiometric separation for13N,11

The radiochemical separation of nitrogen was studied for the determination of ultra trace carbon in gallium arsenide by deutron activation analysis using the12C/d, n/13N reaction. It is based on steam distillation as ammonia and successive substoichi

Ultra trace carbon in gallium arsenide has been determined by deuteron activation analysis. It consists of steam distillation of nitrogen as ammonia and successive substoichiometric precipitation as ammonium tetraphenylborate. It is confirmed that ni
