The apparent suppression of Na/K data obtained with ion-selective electrodes
is due to junction potential and activity coefficient effect, not to bicarbonate binding [Letter], and Coleman RL, Young CC [Reply].
Amemiya, Potentiometric selectivity coefficients of ion-selective electrodes
Construction of different types of ion-selective electrodes
The use of ion-selective electrode
(ISE) is recommended for the following reasons: It measures ionic activity hence it is specific.
2003), using an ion-selective electrode
in equilibration dialyzed and ultrafiltrated samples, reported that the calcium ion concentration in bovine milk was approximately 3.
The potentiometric determination of fluoride using ion-selective electrode
is simple and inexpensive but not readily available in developing countries like Nigeria.
The plasma was analyzed utilizing ion-selective electrodes
and photochemical techniques by a commercial laboratory (Analytics Incorporated, Gaithersburg, MD).
The combined measurement of the four stable halides by the ion-selective electrode
procedure following their chromatographic separation on a strong anion exchanger resin: Clinical applications.
Individual chapters are devoted to determination of total N, extractable nitrate by ion-selective electrode
, ammonium-N, total S, sulfate-S, and chloride.
Additionally, the unit is compatible with the new Rosemount Analytical four-electrode PUR-Sense[TM] conductivity sensor and SMART pH sensors, and allows inputs from ion-selective electrode
1-3 and vide infra) Among these procedures, the ion-selective electrode
assay is the most appropriate for a physician's office.
We used indirect ion-selective electrode
(ISE) methods (Roche/Hitachi Modular) to investigate the effect of hyperlipidemia (cholesterol plus triglycerides) on measurements of sodium, potassium, and chloride and the ability of published formulas to correct for the decrease in measured [Na.
