Sensitivity of Nafion Films to Organic Substances, Especially Ketones

Figure 6

Example of 5 repetitions of the Nafion response to a concentration of 4.4% acetone, where it is shown the typical error of about ±5% on our tests. Subsequent tests presented very similar experimental errors. As can be seen, the tests are quite reproducible. For the sake of clarity in the curves, we do not present this type of data dispersion y the following curves.
