Determination of 14C/12C ratio in volcanic gas
- 1. Kyoritsu College of Pharmacy, Tokyo (Japan)
Description
Determination of 14C/12C ratio in volcanic gas has been aimed at by use of Accelerator Mass Spectrometry (AMS). As a first step, an improvement of the detection limit of 14c/12C was sought for in the analytical procedure that involved the reduction of CO2 into amorphous C. By performing the proton activation analysis of carbon present in various chemicals used in the reduction procedure and by selecting the best chemicals, the detection limit of 4.5 x 10-15 could be achieved routinely while that for the procedure involving direct carbonization of organic material was 3.6 x 10-16. The improved method indicated the presence of 14C in some volcanic gas, and its implication was considered
