Fast-scan cyclic voltammetry and amperometry have been used to measure dopamine release after an electrical stimulation of dopamine neurons that mimics tonic and phasic firing (11, 21).
Constant-potential amperometry is a simple electrochemical technique in which a potential sufficient to oxidize or reduce the molecule of interest is applied to the electrode.
has now been adopted by all major manufacturers of home blood-glucose meters and is taking an increasing share of the market from the traditional colorimetric approach.
The AndCare Pulse Monitor was designed to operate using intermittent pulse amperometry (IPA).
Electrochemical signal amplification: in comparison to the sensitivity of DC amperometry, IPA offers approximately 10-fold signal amplification for picomolar concentrations ([10.
tHcy and methionine (Met) were simultaneously assayed in three separate batches of plasma, using HPLC with electrochemical detection and pulsed integrated amperometry (13,14).
Determination of homocysteine by HPLC with pulsed integrated amperometry.
However, with the ED40 electrochemical detector set for pulsed integrated amperometry
(PIA) mode, any compound with a reduced sulfur atom, including methionine, will generate a signal proportional to concentration .
Electrolytes are determined through ion-selective electrode potentiometry, glucose through amperometry
, hematocrit through conductometrics, and pH through direct potentiometry.
