- | As the distillate lacks the typical mimosa note, it was not suitable for GC-sniffing analyses. However, the absolute could not be directly used because of the presence of nonvolatile (and odorless) compounds. Thus, HS-SPME with a CAR/PDMS 75 μm fiber (extraction of highly volatile compounds) was chosen as sampling method. Fifty-seven odorant zones were detected by the two sniffers during HS-SPME-GC-sniffing. Thirty-seven compounds could be identified with certainty (LRI, MS, odor comparison, and injection of the reference compound). | + | As the distillate lacks the typical mimosa note, it was not suitable for GC-sniffing analyses.
