Features

Measures oxidizable compounds such as catecholamines (epinephrine, norepinephrine, dopamine), indolamines (serotonin, melatonin), ascorbic acid and Fe(II) with exquisite sensitivity, low noise and site specificity

Electrochemical detection

MicroC, WPI™s low cost and elegant instrument for electrochemical detection using carbon microelectrodes, will record the presence and concentration of oxidizable biological compounds in vivo and in vitro. It also features inherently low noise and a sensitivity of 1 millivolt per picoampere of oxidation current. Response time to quantal catecholamine release is less than 1 millisecond. When used with carbon fiber microelectrodes, redox current can be recorded over a range of 1 picoampere to 2 microamperes. The built-in carbon electrode activation feature allows the easy renewal of electrode sensitivity. In addition, MicroC features a low-pass filter and the option of applying DC potential externally. A wide range of compounds can be detected: dopamine, epinephrine, norepinephrine, serotonin, ascorbic acid, etc. Other compounds, such as glutamate, glucose, acetylcholine and alcohol, can also be detected with MicroC using enzyme-modified biosensors. The MicroC Potentiostat is supplied with a carbon electrode probe, with 5 feet triax cable, which accepts 0.79 mm connector pin, and a reference electrode with a 4 mm Ag/AgCl half cell. For applications where smaller half cells are needed, please call WPI for more information.
