Figure 4.

The samples were analyzed using an identical experimental protocol either at Texas A&M on the same instrument but by a different operator (A and B) or at NC State University by another operator and instrument, but the same model of IMS-MS platform (C). Correlation values are listed in Supplemental Table 7 and shown using a color gradient as indicated in the legend at the bottom of the figure.
