Figure 1.

Workflow of suspect screening analysis for 100 consumer products. The color of the text on the right hand side of the figure corresponds to the arrows in the workflow. Samples were homogenized (if necessary) and extracted. Chemical standards were added at 1 µg/g and then GC×GC/TOF-MS was used to characterize the chemicals in the samples via their mass spectra. The spectra were matched, if possible, using the NIST 08 database, and a subset were confirmed using analytical standards. Reported and predicted functional uses of chemicals were used as additional support of chemical identification.
