天游线路检测中心 使用填充柱分析空气中的稀有气体

JMS-Q1000GC Mk II uses a large high-precision quadrupole, enabling highly sensitive analysis It also uses a vacuum system comparable to that of large equipment As a result, packed columns, which require a larger flow rate of carrier gas than capillary columns, can be analyzed without splitting This time, we conducted an analysis of rare gas elements that are present in trace amounts in the air空气主要由氮气（N2；781%）、氧气（O2；209%）和氩气（Ar；09%）组成，仅这三种成分就占体积的999%以上（1）。 Among other constituents, rare gases such as neon (Ne; 182 ppm), krypton (Kr; 114 ppm), and xenon (Xe; 0087 ppm) are known to exist (1)在本报告中，我们将报道使用填充柱的 GC/MS 方法分离和测量空气中存在的稀有气体元素中的痕量 Ne、Kr 和 Xe。
