“…Performance of the developed sensors was investigated using a conductometric experimental set-up and dynamic electrochemical impedance spectroscopy (EIS). The conductometric experimental set-up was developed together with the Institute of Electrodynamics of National Academy of Sciences of Ukraine (Kyiv, Ukraine) and described comprehensively elsewhere [28]. It consisted of a portable differential conductometer equipped with the sensor holder, and a signal processing software.…”

New clinoptilolite‐based conductometric sensors were developed and optimized for selective detection of ammonium in the buffered aqueous solutions. The sensors’ selective elements were prepared by subsequent drop‐casting of zeolite and Nafion on the gold electrode surface. Electrochemical impedance spectroscopy and differential conductometry were used to investigate the sensor performance. As determined in the phosphate buffer solution, the detection limit of the sensors was 30 μM and the linear range 0–1.5 mM. The developed sensors were featured with a simple preparation procedure, high selectivity to normalNnormalH4+ , and storage stability for not less than 126 days.

“…More effective is using parallel-serial conversion of the sensor signals using several ADCs. The instruments, based on this principle allow increasing the sensitivity and speed of measurements for solving important problems in the fields of biomedical measurements and technical diagnostics [12,13].…”

“…The possibility of a deep suppression of power frequency interferences (50 or 60 Hz) by averaging two adjacent samples obtained from each ADC shown and experimentally confirmed. In [13], measurement methods for monitoring the parameters of moving objects under high interference consider when the interaction time of the measurement object with the sensor is limited.…”

“…This sampling speed allows you to select and analyze signals with a frequency spectrum up to 150 Hz using samples of their averaged values with that intervals. To bind the received data stream to real time or to processes in the monitoring object, synchronization of the ADC conversion cycles start is possible by an external signal, which can connect to the microcontroller [13].…”
