| An Analytical Technique for the Measurement of SF6 in Atmosphere and Groundwater |
| SF6 is a colorless, odorless, nontoxic, and nonflammable inert gas with excellent electric insulating and arc-quenching properties, The attraction of SF6 as ideal atmospheric and hydrologic atracer is enhanced by its chemical and biological inertness and its low concentration in atmosphere and hydrosphere. Also, in the field of young groundwater dating, SF6 shows a gradual trend to replace other dating tools such as 3H, CFCs and 3H/3He. It is especially suitble for dating the water recharged since 1970. The high sensitivity of the electron capture detector to SF6 has led the authors to develop and analytical technique for the measurement of SF6. |
