From: Sampling, identification and sensory evaluation of odors of a newborn baby’s head and amniotic fluid

Contour plots of two-dimensional gas chromatograms of the volatile components of odors from a baby’s head (Top) and control (Bottom). GC × GC-MS analysis. Chemically identified spots are encircled. Numbered spots encircled in white correspond to the numbered compounds in Table 1. Nonspecific spots are encircled in black: those with asterisks are solvent- or synthetic resin-related material contamination; those without asterisks indicate siloxanes and/or their derivatives from the adsorbent beads.
