Short summary

The thermal desorption aerosol gas chromatograph (TAG) has been used for in situ measurements of organic marker compounds to identify atmospheric particle sources and transformation processes. Here we identify that inorganic aerosol components (e.g., nitrate and sulfate) and highly oxygenated organic components experience thermal decomposition upon sample heating. This thermal decomposition signal in the TAG system is investigated through laboratory and field data.
