Figure 2: Recovery of compounds using FLEC sampling from galvanized sheet steel, Teflon, and vinyl composite floor tile immediately after application (t=0). Materials show dramatically different adsorption properties. The bottom portion of the bars represent the mean (n=2), whereas the top error portion of the bars represent the recovery range between the two trials divided by two. Graphics script was written in-house using Python software to allow the inclusion of error bars in the three-dimensional plot representations of the FLEC sampling data.
