Short summary
The paper details the design and characterization of a novel instrument for the measurement of particle reactivity and potential bioactivity, the PINQ. It continuously collects particles, regardless of size or composition, directly into a very small amount of liquid with a collection efficiency of > 0.97 and a cut-off size of 20 nm. PINQ has the highest time resolution, of only 1 min, and is very sensitive to various reactive species from the air.
