Short summary
This study addresses challenges in semivolatile organic compound (SVOC) aerosol sampling. Despite its promise, experimental evaluations of the semivolatile aerosol dichotomous sampler (SADS) reveal issues with leakiness, assembly repeatability, and significant wall losses for particles larger than 2 µm. Findings suggest the need for improvements in airtightness, nozzle alignment, and assembly repeatability for the SADS to fulfil its theoretical potential in workplace exposure assessments.
