Abstract:
A two-barrel organic ion-sensitive microelectrode has been developed to electrochemically detect histamine activity. The synthesis of the histamine-sensitive liquid ion exchanger, composed of tetrafluorophenylboron histamine plus 3-nitro-o-xylol, and the construction of the two-barrel microelectrode (0.1-0.5 micron tip diameter) sensitive to histamine based on such an exchanger is reported. The calibration curves, their slope, selectivity, stability and detection limits for different solutions are described. High selectivity for Na+, K+, Ca2+ was observed.

Potentiometry: Types of Electrodes
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...
