| titleOfInvention | High abundance13CO2Standard gas preparation method |
| abstract | The invention provides a high abundance 13 CO 2 The gas preparation method comprises the following steps of firstly mixing solid or liquid 13 After C source is reacted, obtaining 13 CO 2 Gas, reacting with barium hydroxide solution again to obtain 13 Barium carbonate of C; the above-mentioned 13 The abundance value of the C source is more than the natural abundance and less than or equal to 100 percent; then the product obtained in the above step 13 Mixing the barium carbonate of the step C with barium carbonate to obtain a mixture A; mixing the mixture A obtained in the step with calcium carbonate again to obtain a mixture B; finally, the mixture B obtained in the step is reacted with acid to obtain high abundance 13 CO 2 A gas. The gas prepared by the method has the advantages of good uniformity, high stability, low preparation cost, short preparation period, easiness in storage and transportation, capability of being prepared at any time according to needs, small-batch preparation, controllable preparation amount and the like, and is used for detection 13 And when the infrared spectrometer is used, the stability is good and the accuracy is high. |
