General description

Tridodecylmethylammonium nitrate (TDMAN) is a nitrate ionophore which has good selectivity for nitrate more than chloride.
Visit our Sensor Applications portal to learn more.

Application

Selected application examples
TDMAN has been used in preparing liquid ion-selective electrode membrane during coulometric analysis of nitrate from fresh water samples.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Highly lipophilic electroactive component (nitrate ion-exchange) for solvent polymeric electrodes; used in ion-selective field effect transistors; Determination of nitrate in water, soil extracts and in agriculture by ion-selective electrode

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
