Fig. 3From: Headspace analyses using multi-capillary column-ion mobility spectrometry allow rapid pathogen differentiation in hospital-acquired pneumonia relevant bacteriaThe 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 backgroundBack to article page
