ELECTROCHEMICAL MEASUREMENTS OF CELL POPULATIONS
Annals of the New York Academy of Sciences, 1981Determination of cell growth was carried out by a polarographic system. The system was constructed of two platinum electrodes, a saturated calomel electrode, and a thermistor electrode. Responses of the system to the dissolved oxygen, pH, and temperature were examined. Cell growth of S. cerevisiae and M.

An Integrated Sensor for Electrochemical Measurements
IEEE Transactions on Biomedical Engineering, 1986A method for the fabrication of a completely integrated solid-state electrochemical sensor which combines a minature liquid junction reference electrode with a CMOS ISFET is presented. The reference electrode is fabricated by preferentially etching silicon to form a porous silicon frit.

Electrochemical biosensors for extracorporeal measurements
Biochemical Society Transactions, 1991Electrochemical biosensors play a major role in clinical chemistry and medicine. They are widely used for continuous monitoring [ 11, bedside analysis [ 2 ] , urgent care and routine analysis [3]. They have found clinical applications as disposable devices and are almost the only probe types marketed either as a single unit device or as units built ...

Electrochemical Measurement of Corrosion
Corrosion, 1970The results of electrochemical measurements on the corrosion of NiCrFe Alloy 600 and Zircaloy-2 in slightly alkaline lithiated water at 288 C (550 F) are presented. The study showed that, in the presence of dissolved hydrogen at the level of 35 Scc/kg-H2O, the electrochemical techniques could not be used to measure the corrosion rate of NiCrFe Alloy ...

2008
Electrochemical measurements have been playing an increasingly important role in the thermodynamic study of reactions in solution, not only because they provide data that are difficult (or even impossible) to obtain by other methods but also because these data can often be compared with the values determined for the analogous gas-phase reactions, thus ...

Combined Measurement of Electrochemical Noise and Electrochemical Impedance
CORROSION 2003, 2003Abstract Electrochemical noise studies have been shown to be susceptible to asymmetry between the two electrodes that are normally used to measure the current noise, and there is consequently a need for noise monitoring methods that use a single electrode. In this paper such a method is presented.

Electrochemical measurement of phenothiazine-interacted DNA
Bioelectrochemistry, 2004The amount of DNA was measured by using thioridazine, which would be attached to the DNA, as an electrochemical indicator. An indicator (thioridazine) solution, a test solution (DNA solution), and a poly-l-lysine solution were successively placed on a glassy carbon electrode, and the electrode was allowed to dry; DNA was immobilized on an electrode ...

Automated impedance measurements in electrochemical cells
Computers & Chemistry, 1999Abstract In this paper a system is described for impedance measurements in electrochemical cells, integrated by a fast potentiostat, signal generator, digital transient recorder and a computer interface. The treatment of the signal is made by obtaining the correlation between the response cell signal with the in-phase and in-quadrature signals, as is

Electrochemical Measurements of Blood Alcohol Levels
Nature, 1972THE measurement of alcohol concentration in the breath is a more convenient and desirable method of enforcing the drinking and driving laws than the collection and analysis of blood samples. This method is valid because the alcohol concentration in alveolar air is proportional to the alcohol concentration in the blood; it is essential to ensure that ...
