Short summary
A novel chemical ionization methodology for rapid gas–phase environmental monitoring is presented. The usefulness of the new inlet design is demonstrated by measuring various aerosol precursor compounds that are present at very low concentrations by using two consecutive ionization schemes. This new inlet enables the detection of a wide range of compounds of interest with a minimum of effort and at a fast repetition rate.
