Abstract

PURPOSE:To attempt energy saving and increase of capacity of analytical treatment, by automation of a spiking operation of a chemical analysis system. CONSTITUTION:Relative to a powder specimen container 10 transported by a conveyor 11, an istopic structure of the specimen is measured by an alpha-ray analyzer 1, simultaneously, a specimen number is read out by a number reader 2 and these data are introduced into a computer 9. Further, in a spiking operation, a specimen number of a container 12 transported by a conveyor 13 is read out by a number reader 6 and a proper quantity of spikes is added by a titrating device 5 together with data of contents of uranium and plutonium contained in the specimen. Thus, by automation of the spiking operation of the analysis system, a great magnitude of sample treatments of various isotopic structures can be available.
