Usually ion selective electrodes have instructions for their use.

The glass electrode (and other ion selective electrodes) should be calibrated in a medium similar to the one being investigated.

This is important for potentiometric measurements, including ion selective electrodes, because they measure the activity of the analyte rather than its concentration.

Free nitrate ions in solution can be detected by a nitrate ion selective electrode.

It has been used as an ionophore in ion selective electrodes, with good response to Pb and Ni.

Simple ions are often measured with ion selective electrodes, which let one type of ion through, and measure voltage differences.

Potassium concentration in solution is commonly determined by photoelectric flame photometer, atomic absorption spectrophotometry, inductively coupled plasma, or ion selective electrodes.

TISAB is very commonly applied to fluoride ion analysis such as in fluoride ion selective electrodes.

A fluoride selective electrode is a type of ion selective electrode sensitive to the concentration of the fluoride ion.

Similarly, the potentiometric titration of sulfate with barium chloride in various industrial samples can lead to rapid degradation of the indicating barium ion selective electrode.

Furthermore monensin, but also its derivatives monensin methyl ester (MME), and particularly monensin decyl ester (MDE) are widely used in ion selective electrodes.

Potassium selective electrodes are a type of ion selective electrode used in biochemical and biophysical research, where measurements of potassium concentration in an aqueous solution are required, usually on a real time basis.

This study show that continuous monitoring of the sodium concentration in gastric juice with a sodium ion selective electrode is a practical means of assessing fasting DGR, as it is well tolerated and suitable for ambulant use.

The polymer Ion Selective Electrodes were able to determine the concentration of ions by measuring the change of electric potential within the sensor, which is separated from the wet chemistry cell by an ion selective membrane.

Although it is certainly a sound precaution for the determination of sulfide with an ion selective electrode, it might however hamper the development of the blue color if the freshly formed methylene blue is also reduced, as described here above in the paragraph on redox indicator.

Today, the concentration of potassium is determined with an ion-selective electrode.

This definition was adopted because ion-selective electrodes, which are used to measure pH, respond to activity.

The most serious problem limiting use of ion-selective electrodes is interference from other, undesired, ions.

(This is an example of an ion-selective electrode.)

It is the hydrated gel, which makes the pH electrode an ion-selective electrode.

Example: An ion-selective electrode might be calibrated using dilute solutions of the analyte in distilled water.

A potentiometric selectivity coefficient defines the ability of an ion-selective electrode to distinguish one particular ion from others.

Ammonia and ammonium can be measurement using an ion-selective electrode probe and a pH meter.

Lower concentrations of sodium may be determined by atomic absorption spectrophotometry or by potentiometry using ion-selective electrodes.

Mixed with europium fluoride, it is also applied in the crystal membrane of fluoride ion-selective electrodes.

This is called pseudohyponatremia, and can occur when laboratories use the flame-photometric and indirect (but not direct) ion-selective electrode assays.

In modern practice, widely used membranous ion-selective electrodes (ISE, including glasses) are part of a galvanic cell.

Enzyme electrodes definitely are not true ion-selective electrodes but usually are considered within the ion-specific electrode topic.

All these reactions occur inside a special membrane which covers the true ion-selective electrode, which is why enzyme electrodes sometimes are considered as ion-selective.

No ion-selective electrodes are completely ion-specific; all are sensitive to other ions having similar physical properties, to an extent which depends on the degree of similarity.

A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion.

A small amount of salt can be dissolved in cold water and analyzed for fluoride ion by a fluoride ion-selective electrode or ion chromatography.

Ion-selective electrodes are used in biochemical and biophysical research, where measurements of ionic concentration in an aqueous solution are required, usually on a real time basis.

There are four main types of ion-selective membrane used in ion-selective electrodes (ISEs): glass, solid state, liquid based, and compound electrode.

This type of ion-selective electrode is subject to interference from (in declining order of magnitude) rubidium, caesium, ammonium, sodium, calcium, magnesium, and lithium.

The aqueous solution is analyzed for cyanide ion by silver nitrate titrimetric method or an ion-selective electrode method, and ammonia is measured by titration or electrode technique.

Such an electrode has a "double reaction" mechanism - an enzyme reacts with a specific substance, and the product of this reaction (usually H or OH) is detected by a true ion-selective electrode, such as a pH-selective electrodes.

The selectivity coefficient, K is evaluated by means of the emf response of the ion-selective electrode in mixed solutions of the primary ion, B, and interfering ion, C (fixed interference method) or less desirably, in separate solutions of B and C (separate solution method).
