- •
An innovated method based on DANP-IMS was put forward.
- •
Influence of moisture was effectively reduced via an on-line semiconductor cooling inlet.
- •
LOQs for humid H2S were achieved to ≤79.0 ng L−1.
- •
Sewer H2S content in manholes was monitored in real time and its correlation with the resident daily activities was observed.
