1·This instrument can be used for gas analysis and determine of isotopic abundance of light elements.

此仪器可用于气体分析以及轻元素的同位素丰度测定。

2·Spectrometry is preferably used each time extremely low concentrations and isotopic abundance are to be determined.

每当测定非常低的浓度和同位素丰度时总是首先使用无机质谱法。

3·Inorganic Mass Spectrometry is preferably used each time extremely low concentrations and isotopic abundance are to be determined.

每当测定非常低的浓度和同位素丰度时总是首先使用无机质谱法。
