Development of on-line and field dual TD-GC-FID/MS for automatic and continuous VOCs monitoring in ambient air

Chemical Engineering Transactions, 2022
Odorous compounds, such as carbonyl substances, play a major role in ambient air pollution. Monitoring these VOCs is important because some of them have adverse effects on human health and the environment or are, at least, responsible for unpleasant smells.
