Description

Carbonate Ionophore Vii is a highly selective, neutral carrier molecule designed for the potentiometric detection of carbonate ions. This compound is critical for the development of precise ion-selective electrodes (ISEs) and optical sensors used in analytical chemistry and environmental monitoring. It is essential for researchers and manufacturers in the fields of clinical diagnostics, water quality analysis, and industrial process control who require accurate and reliable carbonate quantification.

Application

• Ion-Selective Electrodes (ISEs): Primary active component in membrane formulations for carbonate-selective sensors.
• Clinical Blood Gas Analyzers: Used in sensor systems for measuring bicarbonate/carbonate levels in blood samples.
• Environmental Water Monitoring: Key material in probes for analyzing alkalinity, carbonate hardness, and dissolved inorganic carbon in natural and industrial waters.
• Process Analytical Technology (PAT): Enables real-time monitoring of carbonate concentrations in chemical, pharmaceutical, and food & beverage manufacturing processes.
• Research & Method Development: Serves as a reference standard and critical reagent in academic and industrial research for developing new analytical methods.
• Optochemical Sensors: Incorporated into optode membranes for fiber-optic based carbonate sensing applications.
