General description

ETH 500 is a lipophilic electrolyte mostly used as an anionic additive.
Visit our Sensor Applications portal to learn more.

Application

ETH 500 has been used in the preparation of:
  • molecularly imprinted polymers, which can be used during potentiometric sensing method for determining neutral phenols.
  • copolymer Ca2+ selective membrane cocktail during electrochemical impedance spectroscopic analysis to study the water intake and layer formation in ion-selective electrode.

Other Notes

Highly lipophilic additive for membranes of neutral carrier-based ion-selective macroelectrodes; Additive in membranes of optodes

Calcium is closely related to the oceanic biosphere and carbonate system. Potentiometry based on a calcium-selective electrode (Ca-ISE) represents a promising tool for detection of calcium ion activities in seawater. This technique, however, generally is limited by the low sensitivity

Traditional potentiometric NO3--selective electrodes suffer from a fundamental limitation of the Nernst slope (59.1 mV/dec at 25 °C) due to the relationship between the potential and the logarithmic of ionic activity. Herein, a coulometric signal readout is proposed instead of the
