The measuring cell used is a parallel-plate capacitor with plate spacing 1 cm and plate diameter 13 cm. The measurements were performed at laboratory conditions. A tabstop is used as delimiter between the columns in all txt-files. In addition, the measurement logs are stored as pdf files, so that the filling quantities of the individual measurements can also be traced. Finally, two MATLAB data files are stored, with which the LSTMRNN was trained and tested.enNitrate ConcentrationElectrical Impedance Spectroscopy (EIS)Artificial Neural Network (ANN)Long Short-term Memory (LSTM)Measurements
