| 摘 要： | ＣａＣ２Ｏ４真空热分解中，第一阶段生成的ＣＯ中４７％歧化成ＣＯ２和Ｃ；第二阶段生成的ＣＯ与第一阶段生成的Ｃ发生气化反应，发生反应的比例随样品量增加而增大。用ＣａＣＯ３标定ＣＯ后再用ＣａＣ２Ｏ４标定ＣＯ可以排除这些干扰。本文提出了一个对任意气体标定的方法。

| Abstract: | Almost 47% of CO produced disproportionates into CO_2 and C in the first stage ofdecomposition of CaC_2O_4 heated under vacuum. The CO_2 produced in the second stage reactswith the C produced in the first stage. The proportion increases with the increase of samplesize. A combination system of a EGA and a quadrupol MS was successfully calibrated firstlywith CaCO_3 for CO_2 and then with CaC_2O_4 for CO. A universal calibration method for theEGA-MS System is proposed. |
