Comparison of TD tube peaks which are in common with the mobile GC-MS and occurring only in TD.

<p>Box-and-whisker plots of the relative peak areas from integration of TD tubes Mix peaks in common with the mobile GC-MS samples (left, Median_common = 4.25 x 10^-4, N_common = 183) and peaks which are unique for TD tubes Mix (right, Median_TD = 0.12 x 10⁻⁴, N_TD = 9217). Bold, solid lines indicate medians, boxes range from the lower to the upper quartiles, lower whiskers are defined as max(min(x), Q_1–1.5 * IQR), upper whiskers equal min(max(x), Q_3 + 1.5 * IQR), open circles are outliers, dotted lines depict the means and asterisk indicates the significant difference. The relative peak areas were log transformed, the y-axis of the plot is on original scale.</p
