AUTOMATIC REDUCTION APPARATUS FOR PRE-TREATING SAMPLE FOR RADIOCARBON DATING

摘要

Provided is an automatic reduction apparatus for pre-treating a sample for radiocarbon dating, and more particularly, an automatic reduction apparatus for pre-treating a sample for radiocarbon dating capable of preventing peripheral devices of a liquid nitrogen container from being cooled due to scattering of liquid nitrogen supplied to the liquid nitrogen container of a carbon dioxide collector and preventing the peripheral devices from being heated by heat of a reaction furnace at the time of heating the reaction furnace of a reduction reactor.

主权项

1. An automatic reduction apparatus for pre-treating a sample for radiocarbon dating, comprising:
a carbon dioxide collector configured to choose and collect only carbon dioxide from combustion gas to extract and graphitize carbon within an organic sample; and a reduction reactor configured to reduce the carbon dioxide collected by the carbon dioxide collector to graphite, wherein the carbon dioxide collector includes: a carbon dioxide trap configured to solidify the combustion gas; a liquid nitrogen container configured to cool the carbon dioxide trap; a liquid nitrogen injector configured to inject liquid nitrogen into the liquid nitrogen container; and an anti-scattering member configured to be provided in the liquid nitrogen container and adjacently disposed to the liquid nitrogen injector.
