Seasonal δ³⁴S variations in two high elevation snow pits measured by ³³S–³⁶S double spike thermal ionization mass spectrometry ...
δ³⁴S and sulfate concentrations were determined in snow pit samples using a thermal ionization mass spectrometric technique capable of 0.2‰ accuracy and requires ≈5 μg (0.16 μmol) natural S. The technique utilizes a ³³S–³⁶S double spike for instrumental mass fractionation correction, and has been ap...
