Figure 3: Representative two-dimensional total ion chromatograms obtained from the test probes as collected by FLEC sampling from galvanized sheet steel (top), Teflon (center), and vinyl composition floor tile (bottom) at the 1 hr post-application period. The light areas in the grayscale chromatographic depiction show the baseline signal, whereas the darker gray areas represent the signal values. The signal intensities for all three chromatogram are normalized to allow direct comparison. The 13 test probe analytes that were quantitatively studied are identified in the bottom chromatogram by the numbers given in Table 1. Analysis conditions are further described in the text and in Table 2.
