    SF6 has a molar mass of 146 g/mol and a year is about 31.5 Ms (megaseconds) so the flow is 0.1 g/year x 1year/31.5 Ms x 1 mol/146 g = 22 pmol/s. You need to detect He at the same rate of 22 pmol/s, but the molar mass of He is 4 g/mol, so 88 pg/s or at 1 atm, 25 &C, 540 pL/s. This assumes the tracer gas is pure helium.
