Additional file 1. Comparison of the peaks collected with ITEX and SPME devices. a. Total ion chromatograms (TICs) of VOCs in the HS of A. fistulosum (class01) obtained by ITEX-GC-TOF–MS (left) and SPME-GC-TOF–MS (right). b. VOC peak annotation with RI information obtained by ITEX-GC-TOF–MS (left) and SPME-GC-TOF–MS (right). c. The PCA score scatter plot of VOC profiles of A. fistulosum (class01) obtained by using ITEX-GC-TOF–MS and SPME-GC-TOF–MS. We used three biological replicates (six individual plants per replicate). AU arbitrary unit. Fluorobenzene, 4-bromofluorobenzene, and 1,2-dichlorobenzene-d 4 were used as ISs. Of these, peaks of luorobenzene and 4-bromofluorobenzene were detected (black arrow in Additional file 1).
