3.3. VOCs QuantificationThe third value of the GC-IMS spectra, the intensity, was used for plotting intensity profiles for each location. The intensities of each compound’s monomer, dimer, and trimer were summed, and its average intensity was calculated for all 10 replicates. This procedure was repeated for all 26 detected analytes. Subsequently, the intensity levels of each location were normalized against the outdoor air intensity levels.
