Self-Calibrated Ion-Selective Electrodes [PDF]

open access: yes, 2023
Ion-selective electrode (ISE) potentiometry is reliable only if on-site calibration using a standard solution is performed before the ion measurement. The complex device and operation required for calibration hinder the implementation of ISEs in decen ...

An intracellular analysis of gamma-aminobutyric-acid-associated ion movements in rat sympathetic neurones [PDF]

open access: yes, 1985
Double-barrelled ion-sensitive micro-electrodes were used to measure the changes of the intracellular activities of Cl-, K+, and Na+ (aiCl, aiK, aiNa) in neurones of isolated rat sympathetic ganglia during the action of gamma-aminobutyric acid (GABA ...

Effect of Lipemia on Measured and Calculated Osmolality in Native Lipemic Samples and Intravenous Lipid Emulsion-Added Pools [PDF]

open access: yesNational Journal of Laboratory Medicine, 2020
Introduction: Lipemia are common interferences in clinical laboratories. They particularly cause interference because of the electrolyte exclusion effect on indirect Ion Selective Electrodes (ISE) methodologies.

Membrane-Based Electrochemical Detection of Uranium: A Review

open access: yesSeparations, 2022
The determination of uranium in environmental samples has always been a crucial environmental issue due to its adverse impacts on human life. Electrochemical detection is one of the most suitable methods for directly determining uranium because of its ...

Mean Activity Coefficients of NaNO3 and the Mixing Ion-Interaction Parameters in the Ternary System (NaNO3 + CsNO3 + H2O) at 298.15 K by EMF Method

open access: yesJournal of Chemistry, 2022
Ion-selective electrodes directly respond to the activity of target ions without destroying the existing form of the original electrolyte, so ion-selective electrodes have been widely used in various fields.

Development of miniature all-solid-state potentiometric sensing system [PDF]

open access: yes, 2010
A procedure for the development of a pen-like, multi-electrode potentiometric sensing platform is described. The platform comprises a seven-in-one electrode incorporating all-solid-state ion-selective and reference electrodes based on the conductive ...

Ion-selective electrodes [PDF]

open access: yesPostgraduate Medical Journal, 1999
Sir, In their review of hyponatraemia, Gill and Leese1 identify pseudohyponatraemia as a methodological problem which can lead to a spuriously low sodium. However, their assertion that this is not a problem when an ion-selective electrode (ISE) is used for sodium analysis needs clarification. Two types of methods using ISEs are currently in use within

Ion trapping with fast-response ion-selective microelectrodes enhances detection of extracellular ion channel gradients [PDF]

open access: yes, 2008
Previously, functional mapping of channels has been achieved by measuring the passage of net charge and of specific ions with electrophysiological and intracellular fluorescence imaging techniques.

Dipodal Tetraamide Derivatives of 1,10-Diaza-18-Crown-6 and Alkylmalonic Acids—Synthesis and Use as Ionophores in Ion Selective Membrane Electrodes

open access: yesSensors, 2021
Novel dipodal derivatives of an 18-membered diaza-crown ether with two diamide chains featuring methylmalonic or butylmalonic acid residues were obtained and tested as ionophores in ion-selective plasticized membrane electrodes.

Determination of Calcium and Magnesium in Soils of Samsun-Çarşamba Region by Using Ion-Selective Electrodes

open access: yesTürkiye Tarımsal Araştırmalar Dergisi, 2018
In this study, potentiometric PVC-membrane electrodes were developed with calcium (Ca2+) and magnesium (Mg2+)-selective micro-dimensions with commercially purchased ionophore to determine Ca2+ and Mg2+ ion concentrations in the soil. The potentiometric
