抄録
内容記述 For combustion of samples a closed tube-combustion (CTC) method has been generally and widely used until now, but this method takes much time and labor. Recently we have investigated a CO_2 production and purification system using a commercial elemental analyzer (EA) connected to cryogenic traps, which enables fast combustion and CO_2 purification of samples. We compared δ^<13>C values between closed tube- and elemental analyzer-combusted samples of Oxalic Acid-II (new oxalic acid standard distributed by NIST; SRM4990c) and almost ^<14>C-free oxalic acid (Kishida[○!R]). For the CTC method δ^<13>C measured values tend to increase as sample amount is small relative to CuO amount. This might be due to absorption of more ^<12>C than ^<13>C to an inner wall of Pyrex tube and/or CuO. Furthermore, different δ^<13>C is observed by addition of Sulfix[○!R] to small amount of CO_2. δ^<13>C values measured by the EA method show good agreement with the results using the CTC method, and sample preparation background of ^<14>C is higher in the CTC method than the EA method, suggesting that this newly developed EA system shows high precision and accuracy. However, more detailed study and improvement on the EA system will be needed for different amounts of various standards such as IAEA standards.
