摘要
Method for determinau00c7u00e7o of carbon content in sample, and method for cu00cdclico determinau00c7u00e7o containing carbon material cu00cdclico in sample.The present invention relates to a method for determining a cyclic carbon content in a sample, including a sample, burn to generate carbon dioxide gas and measuring a total quantity of ^ 14 ^ C in the sample from the carbon dioxide gas; burning the sample to confirm The presence or absence of gray, when ash is present.Treating the sample with an acid to generate carbon dioxide gas and measuring a quantity of ^ 14 ^ C from the gas of carbon diu00e1xido; fix the total amount of ^ 14 ^ C in the sample with the amount of ^ 14 ^ C measured by treatment with acid; and calculating a cyclic carbon content in am The oyster from the total quantity of ^ 14 ^ C corrected in the sample.
