Measurement of Ammonium by Ion Selective Electrode (CAT#: STEM-ACT-0111-WXH)

Introduction

Ammonium is an onium cation obtained by protonation of ammonia. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a cofactor. It is a nitrogen hydride, an onium cation and a monovalent inorganic cation. It is a conjugate acid of an ammonia.

Principle

An ideal ion-selective electrode (I.S.E.) consists of a thin membrane across which only the intended ion can be transported. The transport of ions from a high conc. to a low one through a selective binding with some sites within the membrane creates a potential difference.

Applications

• Used for the potentiometric determination of several anions (fluoride, chloride, bromide, iodide ion) and cations (sodium, potassium, calcium ion).
• Used for endpoint detection in potentiometric titration.
• In biochemistry, ion selective electrodes are used for the determination of enzymes and substances which interact with enzymes.
