of the two homologues Methanol and Ethanol allow investigations of the difference
of the kinetics of sorption and desorption, which is mainly based on the different
sizes of the two analytes. Therefore several measurements of single analytes
and measurements of mixtures were performed, which are described in section
22.214.171.124 and in  in detail. Besides of non-optimized
neural networks, the parallel growing neural network framework is applied to
the data resulting in a very small number of variables being selected. This
small number of variables allows the insight into the "black box"
of the calibration by neural networks by the use of a sensitivity analysis.
Additionally, the selection of the variables is confirmed by a brute-force variable
