PAIMS便携式离子迁移谱仪用于痕量六氟化硫(SF6)快速检测

The ion mobility spectrometry technique offers advantages like high sensitivity (ppb range), fast response (ms range), compact design, operation in atmospheric pressure and ability to separate the isomeric compounds. In this short report we demonstrate the sensitivity and fast response of IMS for Sulfur hexafluoride (SF6).

离子迁移率谱技术具有高灵敏度（ppb范围）、快速反应（ms范围）、设计紧凑、在大气压下操作以及能够分离异构化合物等优点。在这个简短的报告中，我们展示了IMS对六氟化硫（SF6）的灵敏度和快速反应。

Sulfur hexafluoride (SF6) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom, molar mass of SF6 is 146.06 g/mol.

六氟化硫（SF6）是一种极强的持久性温室气体，主要被用作电绝缘体和电弧抑制剂。它是无机的、无色的、无味的、不可燃的和无毒的。SF6有一个八面体的几何形状，由六个氟原子连接到一个中心硫原子组成，SF6的摩尔质量为146.06g/mol。
