Developments in accelerator mass spectrometry (AMS) method for 182Hf
182Hf accelerator mass spectrometry (AMS) HfF4 injector solid-phase reaction
2009/8/14
The present detection limit for 182Hf at CIAE HI-13 AMS systems could not satisfy various applications (e. g. detection of a nearby supernovae signal). Therefore, techniques were developed in this wor...
On the isolation of elemental carbon (EC) for micro-molar 14C accelerator mass spectrometry: development of a hybrid reference material for 14C-EC accuracy assurance, and a critical evaluation of the thermal optical kinetic (TOK) EC isolation procedure
elemental carbon EC TOK
2009/2/18
The primary objective of the research reported here has been the development of a hybrid reference material (RM) to serve as a test of accuracy for elemental carbon (EC) isotopic (14C) speciation meas...
