AIR EXTRACTION SYSTEMS FOR ICE CORE AND CO_2 AND CH_4 CONCENTRATIONS IN THE PAST ATMOSPHERE
P(論文) Dry and melt extraction systems have been developed to determine respectively the CO_2 and CH_4 concentrations of ancient air trapped in the polar ice core. The day extraction system was confirmed to be capable of crushing a core sample of 1kg to fine powder within 2 min, and its air extractio...
