文摘

An integrated automation system of routine instrumental neutron activation analysis (INAA) with three HPGe detectors has been built at China Institute of Atomic Energy. This system is mainly composed of sample counting system, pneumatic transfer system, software control and analysis systems, etc. The characteristics include more than 200 samples can be controlled for a batch of INAA with three detectors simultaneously, sample counting position can be optimized automatically according to the counting dead time, the real-time tracking and the high consistency between the spectrum and counting sample are possible to be realized through radio frequency identification tag.
