New Chemometric Approach Using Data Obtained by a DMFC Device to Qualitatively and Quantitatively Determine Organic Molecules

摘要

In this communication first results are reported: seven organic molecules were considered: (3 alcohols) methanol, ethanol, propanol, (2 antibiotics) chloram-phenicol, imipenem, (and 2 important biologic molecules) atropine and cortisone. For quantitative analysis seven different calibration curves were built (one for each molecule), showing different calibration sensitivity, which allows the quantitative determination of the seven organic molecules. For the qualitative analysis data from each of curves, obtained through the fuel cell, which represent the sensor's response to each of the molecules considered, where processed by chemometric methods, so that it was possible to directly identify and recognize each of the seven organic molecules.
