Quantitative gas analysis by quadrupole mass spectrometry is used widely in the study of fluid inclusion volatiles, but the currently available instrument calibration techniques have a number of limitations. We describe a new method to overcome these by employing custom‐machined stainless‐steel calibration volumes that fit into modified bellows valves and can be filled on the high‐vacuum prep line of the instrument. This allows the calibration gas to be introduced in a pulse‐like fashion, replicating a burst of sample gas from a ruptured fluid inclusion.

一种使用四极质谱仪对流体夹杂物进行定量气体分析的新校准技术。

通过四极杆质谱进行定量气体分析被广泛用于流体包裹体挥发物的研究，但是当前可用的仪器校准技术存在许多局限性。我们介绍了一种克服这些问题的新方法，方法是使用定制的不锈钢校准体积，该体积适合改装的波纹管阀，并且可以在仪器的高真空制备管线上填充。这样就可以以脉冲形式引入校准气体，从而从破裂的流体包裹体中复制出一阵样气。
