Figure 6.

Example of the signals generated by the nCB-based hybrid gels during exposure to volatile vapors and a collective accuracy prediction plot for the 12 VOCs yielded by all the tested hybrid gels, (a) exposure to chloroform, (b) exposure to toluene, and (c) exposure to acetonitrile. Seven cycles are depicted here, each of 5 s of exposure (gray columns) and 15 s of recovery with ambient air and (d) bars prediction plot represents the prediction accuracy of the automatic classifier trained and tested with the collected e-nose signals.
