Description of the data and file structure

This dataset contains the data required to replicate atmospheric sulfur dioxide determination by inductively coupled plasma mass spectrometer in collision cell technology mode. O2 flow rate on CCT mode was optimized to realize optimal S/N ratio at m/z 48 (32S16O+). 5 nmol mol-1-1.00 μmol mol-1 SO2 in nitrogen gas reference materials proved the feasibility of the method under different conditions to prepare SO2 concentrated solution samples such as sampling flow rate, the volume of concentrated solution, the number of PFA bubble absorption bottles, the composition of concentrated solution and so on. For the purpose of monitoring SO2 level in the ambient atmosphere, sulfur-containing gases and other co-existing air pollutants that may cause interference were also evaluated. The assay of atmospheric levels was a proof to validate the analytical performance of the proposed strategy on SO2 quantification with ICP-MS in a practical application.
