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

Two novel all-solid-state potentiometric sensors for the determination of azide ion are prepared and described here for the first time. The sensors are based on the use of iron II-phthalocyanine (Fe-PC) neutral carrier complex and nitron-azide ion-pair complex (Nit-N₃-) as
Potentiometric sensor for determination of neutral bisphenol A using a molecularly imprinted polymer as a receptor.
