Method and device for determining 14c in solid and liquid samples |
| abstract |
The invention relates to a method and device for determining 14C in solid and liquid samples. The sample is decomposed and dissolved in a sealed airtight vessel by addition of chromic acid, wherein the resultant CO2 is driven off. The CO2 is completely absorbed from the gas phase in a small amount of caustic soda also located within the sealed vessel (within 24 hours) with formation of Na2CO3 and NaHCO3. The14C activity of the caustic soda is subsequently measured in a liquid scintillation spectrometer. |
