This method is extremely sensitive and the limit of detection for the CFCs are 0.005 x10 12 moles per kilogram of water (pmol kg 1). The limit of detection for SF6 is even more sensitive at 0.05 x 10 15 moles per kilogram of water (fmol kg 1). Precision values for all three CFCs are 2 % or less. SF6 precision is 5% or less.
