sf6 gas Lab: Groundwater and Soil Air | Lamont-Doherty Earth

SF 6 is separated from other gases by a molecular sieve 5A column at room temperature. Currently, water samples are collected using glass syringes. After equilibration of the gases dissolved in the water with a head space in the syringe, the gas samples are injected directly into the GC system via the sample loop method. With this method, the minimum and maximum concentration typically measured are 8 fM and 8E4 fM, respectively (1 fM = 1 femtomoles = 10 E-15 mol/L).Get price
