The positions of all 30 VOCs analysed in this study in a representative topographic plot of MCC-IMS measurements of the headspace over sterile LB medium in (a) the positive and (b) the negative ion mode of the MCC-IMS device. The remaining VOC signals and plot areas did not change during the experiments and were considered to be part of the volatile background
