Also, there are a lot of companies that make ion-selective electrodes so any of these companies would be perhaps be interested in putting this device into their portfolio.
Simple analytical tools such an ion-selective electrodes offer a direct measurement of active substances even in colored or turbid solution without previous extraction.
Their topics include trans-membrane ion fluxes for lowering the detection limit of ion-selective electrodes, ion transport and selected ion channels in biological membranes in health and pathology, plant photosystem II as an example of a natural photovoltaic device, molecular properties and reaction mechanisms of multi-copper oxidases related to their use in biofuel cells, and electrochemical system controlled by enzyme-based logic networks as a step toward biochemically controlled bioelectronics.
05, indicating that there is a significant difference between the electrolyte values of both sodium and potassium using the flame photometer and ion-selective electrodes.
Fluoride ion-selective electrodes respond to the fluoride concentration in a non-linear relationship following the Nernst Equation [18].
Similar devices, called ion-selective electrodes (ISEs), are already used by medical researchers and athletic trainers.
It is gratifying that there is to be a link between the Hankow Union Hospital in Hunan Province and the College of Medicine of Swansea University, especially as it is now nearly 30 years since I gave a course of lectures on electrochemistry and ion-selective electrodes (with roles in blood electrolyte analysis) to an audience of several hundred at Hunan University in Changsha in October 1983.
The techniques and theory behind ion-selective electrodes will not be included here; the interested reader is referred to books and reviews on this subject (Koryta, 1972, 1977, 1984, 1986, 1988, 1990; Thomas, 1978; Covington, 1979; Ammann, 1986).
The often-cited reference range for the anion gap of 8 mmol/L to 16 mmol/L, since lowered to 3 mmol/L to 11 mmol/L following the implementation of ion-selective electrodes for measuring electrolytes, should be used only as a rough guideline.
The most commonly used methods to detect serum lithium are ion-selective electrodes (ISEs) and flame emission photometry.
