Title: EXPERIMENTAL DEVICE FOR PREPARING LIQUID SAMPLE OF CARBON-14 IN RADIOACTIVE GRAPHITE
Abstract:
Disclosed is an experimental device (10) for preparing a liquid sample of carbon-14 in radioactive graphite. The experimental device comprises: a pressure-bearing steel cylinder (101), a top end cover (102), a sealing cover (103), two electrodes (104), an ignition wire (105), a support for a sample crucible (106), and an air inflation and discharge valve (107). The experimental device further comprises an adsorption device (110) for tritium-containing steam, wherein the adsorption device (110) in use is arranged inside the pressure-bearing steel cylinder (101), such that an internal space of the pressure-bearing steel cylinder (101) is divided into a first space (115) and a second space (116), and the adsorption device (110) has multiple through holes, the first space (115) and the second space (116) being communicated merely by the adsorption device (110).
